Advantages of using grub2

What are the advantages of using grub2 over just grub? Why would I want to upgrade?

The coolest thing about Grub2, as far as I'm concerned, is that it supports booting off of software raid natively (and LVM volumes as well, I think), the downside is that there's really not that much detailed documentation available on how to do that(at least at the time I tried it) ... or on Grub2 configuration in general (again, at the time I tried it), I tried to use it when I got some extra hard-drives and began running on Software Raid, but in the end I gave up and went back to Grub, because I already knew how to use it and the work-around's to make Grub boot software raid are really not that bad.  (you just need a separate non-raid or raid 1/boot partition).
I think sometime in the not too distant future (perheps next Sunday, AD) Debian/Ubuntu are switching to Grub2.  I imagine the documentation situation will get better if that happens, and I might try and switch again.  For now, Grub gets the job done for me.

  • If I use the same iCloud account for my ipad and iPhone, will changes I make on one change on the other as well?  I'm not sure of the advantage of using teh same iCloud for both devices.

    No, it only mirrors changes to synced data.  This includes mail, contacts, calendars, reminders, safari bookmarks, notes, iWork documents and data, and photo stream photos (assuming you choose to sync all this data).  Changes to iTunes data such as music, apps, podcasts, etc., are not synced using iCloud.  In your example, if you delete an app from one device it will remain on the other until deleted there too.

    What are the advantage of using a passive monitoring technique

    Hi Plawansai,
    I saw your question that is still unanswered.
    I believe an advantage of using a passive monitoring technique is that it won't interfer with live traffic, as it does not inject traffic into the network or modify the traffic that is already on the network.
    One drawback anyway, is that post-processing time can take a large amount of time with passive monitoring!
    A combination of the two monitoring methods seems to be the route to go.

  • What are the advantages of using Map IDs?

    Hi:
    I am trying to find out the advantages for using map ids as
    opposed to just using the file names for the topics, but I couldn't
    find this information in the RH7 Help or the forums. Can you please
    list the advantages and disadvantages.
    Also, I am describing how I wish to implement the context
    sensitive help feature for my application and you can tell me which
    approach is better. We make an application that is packaged within
    a Java IDE. We want to launch context sensitive help topics from
    the wizards and cheat sheets. Now, this context sensitive help can
    be either be installed on the local machine or network (file://
    protocol) or available on our portal (https:// protocol). We do
    have the infrastructure in place to let the user decide whether
    he/she wants to access the local help topic or the one over the
    internet. Will map ids work for both the scenarios?
    Thanks,
    K

    It sounds like your application call needs to call an online
    version of the help first and if this is not available to point to
    a local copy. Is that right? If so, how this happens is entirely in
    the hands of your developers. I know it can be done, just sketchy
    on the actual procedure.
    As far as the CSH in the help is concerned, you can use
    mapids for both versions of the help if you want. If using webhelp
    you'd do well to check out
    this
    link on Peter Grainge's site.

  • What is the advantages of using Flexconnect groups

    what is the advantages of using Flexconnect groups in WLC?
    Reg,
    Ezra.

    Pls refer this document for more detail about these features
    http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob73dg/emob73/ch7_HREA.html#wp1091114
    FlexConnect is one mode an AP can operate, typically deployed in Branch setup where you do not have a controller at branch site. Those AP can register to a controller at your HQ or main site. So traffic will terminate at your branch switch instead of tunnel back to HQ-WLC.
    If you want roaming within your branch FlexConnect AP then you have to put those AP into a FlexConnect Group. Then only key information shared among those AP to facilitate fast roaming.
    Pls do not forget to rate our responses if you find them useful.

  • What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

    Hi All,
    I am new to TestStand. Still in the process of learning it.
    What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
    Thanks in advance,
    LaVIEWan
    Solved!

    Hi,
    Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

  • Advantages to using iMessage?

    Hi, are there any advantages to using iMessage if you're on a plan with unlimited taik and text? iMessage uses data on the 4GLTE network if one is not on a Wi-Fi connection, so why use iMessage when you have unlimited text messages? I'm curious; I like iMessages, but why use data if you're on a tiered plan if you don't have to?

        MaceWindu57, we want you to take advantage of every benefit available on our wireless network. The iMessaging feature works great for group text conversations and sending/recieving messages to iPads or iPods. Additionally, this option is also awesome when you're in a location that has no wireless reception as you can send iMessages over Wi-Fi instead. Lastly, iMessaging is a free way to send/recieve text messages for those that don't subscribe to a Messaging Plan.

  • What are the advantages of using ENC for a datasource

    Other than eliminating a tight binding between a EJB and a datasource , what are
    the other considerations and/or advantages of using JNDI ENC to define a datasource
    reference vs a direct lookup of a Datasource in the EJB implmentation?
    For example, are their performance advantages by the datasource being cached in
    JNDI ENC?

    Hello Bryan,
    Basically the main advantage is to not have the tight coupling between the EJB
    and the particular JNDI name that it's bounded to. Please refer to a previous
    post where I addressed this issue (perhaps a few days ago on this newsgroup).
    In addition, you will always gain performance improvements by caching the remote/local
    home objects for your EJBs.
    Best regards,

  • Advantages of using partitions for tasks

    I like my setup on one partition.  But I'm wondering, are there advantages to using separate partitions for /, /home, /boot, and swap?
    Simple question, but I'd like to know the answer from many sources, cause it seems like the type of question that has multiple answers.

    My laptop and a little server in the home which I'll set up to the face the internet at some point so I can get to files/music etc have split partitioning: / /usr /var /home /tmp (via tmpfs) and separate /boot (needed for lvm/encryption/funny filesystems). I set up the partitions on advice of some of the hardening guides (see wiki). As well as allowing for problems with huge log files crashing the system as mentioned above, the idea is to have separate partitions to restrict what can be done in each area of the file system via mounting options in fstab. Eg, one of the options you could give to /var and/or /home would be noexec, so no exectuables/scripts could be run. If someone breaks in, it should make it harder to gain complete control.
    It's prob overkill, but I am a big fan of peace of mind It doesn't take much longer to set up (make it lvm so you don't have to worry about getting the partition sizes wrong) and it doesn't hinder how my system runs in any way.

  • Advantages of using OPPQ tcode

    Hi ,
    We use OPPQ tcode to maintain MRP parametes with respect to a specific plant and we also have individual tcodes to maintain MRP paramters - like "MRP Controllers, Planning Horizon,Floats,Rescheduling etc". Is there any specific reason/advantages to use OPPQ tcode to maintain MRP parameters instead of using individual tcodes to maintain MRP parameters?. Thanks in advance.

    Using OPPQ we can copy the MRP parameters of an existing plant to a newly created plant in one-go.
    If we know the parameters of an existing plant it makes sense to copy it directly through this txn instead of individual maintenance.Also any 'particular' data can be changed as per your requirement in the new plant easily.
    Apart from the above advantage the 'reference plant' option in OPPQ helps us in reduced data maintenance w.r.to 4 parameters namely Plg cycle/Plg calendar/ROC profile/Rounding profile.
    All we need is to create the data in reference plant which is then made available for the planning/new plant automatically.

  • Advantages of using BPR in an SAP project

    Hi
    Could anyone tell me what are the advantages and significance of using the Business Process Respository (BPR) while starting an implementation Project (or template project). Lets say as opposed to NOT using the BPR. What are the pros and cons of the two approaches? And how reliable are these BPR contents?
    Appreciate your answers
    Drake

    Hi Drake,
    BPR comes from SAP and delivered via Software Component ST-ICO. Periodically, SAP keeps upgrading this component and in my view, one of the best enablers of Solution Manager.
    From a Project point of view, if you use BPR provided content, at Scenario, Process level, it inherits all 'associated' assignments, like Transaction Codes, IMG nodes relevant for a given Process Step. Also, it loads any other accelerator documents from SAP in General Documentation Tab.
    These contents are helpful for Business Process Monitoring (BPM) too when you want to 'inherit' the Processes and Process Steps defined in Project into Solution. There are standard metrics that SAP provides for process steps in BPM that would be more easily compatible if a project had got the same terminology.
    BPR, however, isn't as comprehensive as we may like it to be. It's rich on some areas and frugal on certain others.
    In terms of 'reliability', well there is no specific aspersions that could be cast  on it
    If it's rich, it's visible and useful; where it's not good enough, we can always add some content and still make some good use of it.
    Another advantage of using BPR is that when a new version of BPR is downloaded and applied, using SA_PROJECT_UPGRADE transaction, the system will offer a chance to see areas which are impacted by a change and those can accepted in SOLAR01/02.
    So, BPR-led content can always be kept up-to-date.
    In my personal experience, I have realised that 2 consultants can easily have 4 opinions! On ever fluid concepts like Scenario, Processes etc. to attain a convergence of thoughts and minds is a difficult proposition. BPR allows for a project to close the gap and adopt SAP ways of definition and helps jump-start the project. The time saved is better used in value added areas or in rigorous testing and training !
    The only firms/ projects which may want to shy from BPR could  be those:
    - who have a fairly well established vocabulory of defining their day to day processes and where retrofitting SAP definitions can be counter productive
    - who have traditionally used advanced platforms like ARIS or other tools
    - who work in industries inadequately represented by SAP

  • Advantages of using "Exchange" account type

    I'm trying to determine the best way of using Mail in a predominantly Outlook/Exchange environment. I see that Mail has an "Exchange" account, and describes it as follows:
    An Exchange account allows you to connect to your Exchange server via IMAP, and if you enter text in the Outlook Web Access Server field, Mail filters non-email related content from the server.
    Is this really all it does? Hide the folders like "Journal", "Notes", etc? Why doesn't it hide "Calendar"? Is there some flag one can set on a folder to mark it as an Exchange folder?
    Are there any other advantages of using the "Exchange" account type as opposed to an IMAP account?

    Turns out the Exchange account type ignores folders like Contacts, Journal and so on (but not Calendar or Sync Issues. Grr.

  • Advantages of Using Secure Connect in Cisco Jabber Version 9.0

    Hello,
    About a month ago we deployed Jabber for iPhone.   For VPN we used Cisco AnyConnect,certificate authentication and VPN on demand.   We used our MDM to deploy the certificates and AnyConnect configuration.    So far everything is working as designed.  Now with the release of version 9, Secure Connect is an option and I was wondering what are the advantages of using Secure Connect? 
    Thanks

    Hi Manrico,
    Are the all the systems using the same firewall policy. It could be one of the rules configured in the SEP client. What build version are you running? Are all systems using the same version of VPN client? As Parminder stated, you should disable the firewall and check behavior.
    If the firewall is found to be the cause, you can troubleshoot by adding an "Allow All" rule to the top of the SEP policy. Moving the rule down one line at a time until the problem occurs again. Once that happens, you will have narrowed it down to the rule just above.
    Let us know how it goes for you.
    Best,
    Thomas

  • Advantages of using labview in embedded application when compared to c ?

    Hello all,
    I am looking to develop embedded application with help of labview programming
    Started with Lm3s8962 evaluation board.
    So i would like to know
    1 Advantages of using labview in embedded application when compared to c ?
    2 Can we deploy the code in any kind of  controller by writting drivers for it ?

    hello, the LM3S8962 microcontroller is a good sispositivos for developing applications of medium complexity, according to your questions:
    1. if you work applications with embedded systems will save labview time in prototyping, we know that if you work with a company specific microcontroller, you must learn the language with which you are working Asm, Basic, C, then if you change hardware again start adapting your code in the libraries of the new compiler. Labview does not happen. 
    2. Labview only works with some microcontroller manufacturers and specific models.
