[SOLVED] How to use GPT GUIDs for referencing partitions in /dev?

Hi all,
         I wanted to know whether it is possible to use Unique Partition GUID of a GPT partition to setup /dev/disk/by-part-uuid (something like that) and using that path in the bootloader config's 'root= ' kernel parameter.
It is possible to obtain those GUIDs from gdisk (or maybe from blkid in util-linux-ng - not sure). But how to make udev setup /dev/disk/by-part-uuid like dir with these GUIDs.
Main info http://marc.info/?l=linux-hotplug&m=129425482207292&w=2 and http://git.kernel.org/?p=linux/kernel/g … b78fc0e100 (currently in 2.6.37 only - but this commit will not work since in Arch initramfs is used). Thanks in advance.

Encypted partitions (not that I use). Also searching will be faster (although not noticable), as parsing partition table is faster than parsing each filesystem and obtaining UUID. See http://www.mail-archive.com/grub-devel@ … 15218.html and http://www.mail-archive.com/grub-devel@ … 15228.html

    Hi,
    Take one integer value attribute in the context of view
    when you r performing action on POP1 set it's value to 1
    when you r performing action on POP2 set it's value to 2
    create one method which receives integer argument, say diaplay(int a)
    In the action call display(wdContext.currentContextElement().get<intvariable>()) by passing the value in the context attribute
    in display() method, Check the value of integer variable..
    if it is 1 then perform action related to POP1
    if it is 2 then perform action related to POP2

  • How to use Web Serivce for not jsr 172 phone

    Hi:
    Is anyone know, how to use web service for phones that only have standard J2ME package installed (without jsr 172 web service packagenstalled)?
    thank you

    Hi,
    I think you need to write the code for this from scratch (built on top of existing HTTP functionality). There may be open-source J2ME code you could use. I've never tried this so I'm afraid I don't know any more. But maybe that is what you were asking... i.e. does anyone have code that does this already...

    The Java Function Activity Agent is not certified for Oracle Workflow embedded in Oracle Applications.

I suggest you contact Oracle Support or Oracle Consulting for assistance.

    GSX, if you're referring to Apple's service by that name, is available only to employees of Apple-authorized service providers or self-servicing accounts. Unless you are employed by such an organization, you cannot access GSX. If you are employed by such an organization, they should set you up and give you the appropriate login information.
    If you are interested in becoming a certified Apple hardware technician, you can find information here:
    http://training.apple.com/certification/acmt
    Please note, though, that certification does not in and of itself give you access to any of the Apple resouces for support organizations; diagnostic tools, parts ordering, etc. You again must be employed by an authorized Apple support provider before you can gain such access.
    I have no idea what "knowlaged" might be.
