Server vs. Desktop kernel config?

Relatively new arch user here, so feel free to flame me for RTFM. I have been reading the docs, but haven't stumbled across anything related to this issue.
I'm going to be installing arch on servers and desktops, and noticed there is only one kernel package, presumably optimized for desktop users. I'm wondering if this means that I need to configure a different kernel package for my server installs? For example, should I be be using a different default scheduler (i.e. deadline instead of cfq), or, maybe the kernel devs have already resolved this at runtime.
Also note the comment that I've heard frequently "don't run arch on production servers" doesn't apply. Save for critical security updates, we already stage all deployments (even using Ubuntu) on testing systems for at least a month before deploying to production. I expect the arch servers will be just as stable as anything else out there (probably more, actually).

Some kernel patches to consider:
BFS for desktop responsiveness (here's the patch I've put together for kernel 3.10)
PHC for CPU undervolting - cooler is always better
BFQ disk scheduler
Full AppArmor support

Kernel Config for Server

Arch's default kernel config is well suited to desktop performance, but what about the server? Ubuntu server lists these items on their Kernel Features page:
* The Server Edition uses the Deadline I/O scheduler instead of the CFQ scheduler used by the Desktop Edition.
* Pre-emption is turned off in the Server Edition.
* The timer interrupt is 100 Hz in the Server Edition and 250 Hz in the Desktop Edition.
* The Server Edition is optimised for i686 processors while the Desktop Edition is optimised for both the i586 and i686.
* Virtualization is better supported in the Server Edition through the enabling of IPC namespaces.
* Multiple routing tables for the IPv6 protocol are also supported in the Server Edition.
* For 32-bit systems the Server Edition is configured to use PAE which allows addressing up to 64GB of memory while the Desktop Edition is configured for 4GB.
So if you were making a "Server Edition" of Arch, what would you change?

imho, with all my respect to arch as a great desktop distribution, i would not run arch on any production server.

Default kernel config question: acpi video freezes my laptop

Hi,
I have a Samsung X60 laptop that freezes when the acpi video module is loaded. The default Arch kernel config (and the derived suspend2 one) includes as built-in some of the acpi code (including the video bit). I'm interested to learn why they are included as built in, and if there is a way to selectively skip the acpi video built-in bit of code? (more selectively than acpi=off as a kernel parameter). Would it be reasonable to request a change to the default kernel config?
cheers

bugs.archlinux.org to make sure its fixed.
the acpi video module is reasonably new and it can be compiled as a module iirc, so it shouldnt be any harm to have it compiled as such.

Custom kernel config and fsck error

Why does arch kernel config pass while custom kernel config fail the fsck during boot? Udev obviously populates /dev/sda* with the archlinux kernel config while the custom kernel config populates /dev/hda*. Is there a reason for this behavior related to the config file or is it a initscript based on /etc/fstab related issue? I have the two different kernel configuration files for the i686 machines, just in case someone can figure this out.
http://aur.archlinux.org/packages/longe … ig-longene
http://aur.archlinux.org/packages/longe … -archlinux

Check to make sure that it is not because of the system time being changed. It will complain about this if it has changed and fail the first filesystem check.

Robohelp server or desktop

hi there,
We have to write help files for our various products.
What are the major difference in server and desktop version.
Precisely, i am looking for anwers of :
1. can we create independent (does not look for robohelp
server to get data) executable files (.exe, .htm) so that we can
link it to our application software.
2. if we buy RoboHelp Desktop, then what are we MISSING...if
we buy robohelp server
thanks for your expert knowledge sharing in advance.

While many of the RoboHelp Server administrative tasks can be performed from the browser-based Web Admin app, certain basic configuration tasks require Configuration Manager. That app is strictly accessed from the server itself. Most folks set up a Windows Remote Desktop Connection to the server desktop and use it that way. Of course this requires getting permissions and access to the server from your desktop.
Is this what you mean?

Can I adjust the kernel config-file? [SOLVED]

so i kicked out linux-3 kernel and installed the "aufs_friendly kernel" with the aufs2 package all went well...after the reboot i got an error "acer_wmid" failure .
my question can i rebuild the kernel WHITOUT the "acer_wmi" part from the config-file within the kernel-source ????
# Altera FPGA firmware download module
CONFIG_ALTERA_STAPL=m
CONFIG_X86_PLATFORM_DEVICES=y
CONFIG_ACER_WMI=m <<==== compiled as module and i want to get rid off...
CONFIG_ACERHDF=m
CONFIG_ASUS_LAPTOP=m
CONFIG_DELL_LAPTOP=m
CONFIG_DELL_WMI=m
CONFIG_DELL_WMI_AIO=m
because in the heather of the file
# Automatically generated make config: don't edit <<==== THIS ??!!

anybody any ideas ??

Uncomment the "make menuconfig" line in the PKGBUILD or run that command when creating your kernel config. This will bring up the console config utility. Navigate to Device Drivers --> all the way down to X86 Platform Specific.. Toggle Acer WMI Laptop Extras using the spacebar.
gonna try ...i'd blacklisted the module for now.
You can also edit the config file directly and change the 'm' to a 'n' This will work but the reason it's not recommended is because some options are dependent on other kernel options.
tried that one .....no success
[EDIT:] Uncomment the "make menuconfig" line in the PKGBUILD = worked for me

Checking kernel config

Here are a couple of stupid shell (zsh) functions that I've been banging on to help check out the current kernel config.
Just wondering if anyone thinks this might be useful and worth expanding upon.
kc - returns any KConfig help text for the specified kernel option (don't put CONFIG_) in front
Example:
[✍] ~ $ kc TMPFS
config TMPFS
bool "Virtual memory file system support (former shm fs)"
depends on SHMEM
help
Tmpfs is a file system which keeps all files in virtual memory.
The code:
function kc() {
export SEARCH_TERM=$1
find /usr/src/linux-`uname -r` -name Kconfig -print0 | xargs -0 perl -ne '
$/ = "";
while (<>) {
while (/^(config $ENV{'SEARCH_TERM'}\s.*)/sgm) {
print "$1\n";
unset SEARCH_TERM
kcc - uses the above to go through every kernel config (that is enabled or built as a module)
Example:
[✍] ~ $ kcc
config 60XX_WDT
tristate "SBC-60XX Watchdog Timer"
depends on X86
help
This driver can be used with the watchdog timer found on some
single board computers, namely the 6010 PII based computer.
It may well work with other cards. It reads port 0x443 to enable
and re-set the watchdog timer, and reads port 0x45 to disable
the watchdog. If you have a card that behave in similar ways,
you can probably make this driver work with your card as well.
config 64BIT
depends on TILEGX
def_bool y
[...snip...]
The code:
function kcc() {
for i in `zcat /proc/config.gz | perl -ne '/^CONFIG_(.*)=[y|m]/; print "$1\n";' | sort | uniq`
do
kc $i
done

Doesn't it work out-of-the-box? The latest kernel should have a driver for your soundcard.

Need help kernel config M4A785TD-EVO

Hi,
My SSD died the other day and I got a replacement (a samsung 840 128Gb). I re-installed but unfortunately I didn't keep a copy of my kernel config file so I am creating a new one but somehow I can't get it to work. I want it without a initrd. I also have an IDE drive (/dev/sda). The SSD is /dev/sdb.
I get a kernel panic on: Unable to mount root fs on unknown-block(8,18). I don't know what option I'm missing.
I have:
Device Drivers
<*> Serial ATA and Parallel ATA drivers
<*> ATA SFF support
<*> ATI PATA support
Device Drivers
-*- I2C support
I2C Hardware Bus support
<*> Intel PIIX4 and compatible (ATI/AMD/Serverworks/Broadcom/SMSC)
And also:
CONFIG_SATA_AHCI=y
If someone can point me at which option I might be missing that would be great.
Thanks.

problem resolved. the default arch sees my ssd as /dev/sdb and the IDE as /dev/sda when my kernel sees it the other way around, the ssd as /dev/sda and the IDE as /dev/sdb.

Can I use System Center 2012 Endpoint Protection in "Windows Server Remote Desktop Session Host" without buy the license ?

Can I use System Center 2012 Endpoint Protection in Azure Virtual Machine Gallary's "Windows Server Remote Desktop Session Host" without buy the System Center 2012 Endpoint Protection license ?
I want to protect my Azure RemoteApp against the malware.
System Center 2012 Endpoint Protection installed Azure Virtual Machine Gallary's "Windows Server Remote Desktop Session Host".
Now, I try to build Azure RemoteApp template by using the Azure Virtual Machine Gallary's "Windows Server Remote Desktop Session Host" .
Regards,
Yoshihiro Kawabata

Hi Yoshihiro,
Unless and until Microsoft modifies the license terms for System Center 2012 Endpoint Protection and/or modifies the Online Services Terms (OST) and/or other document explicitly saying that use is included with the Azure RemoteApp (ARA) monthly
fee I recommend you assume as that it is
not included and license it separately for ARA if that is even possible, which is a separate question.
For licensing it is best to be cautious and make decisions based on the official documents that are available that govern use of the software and services involved. At this moment I'm not able to find a Microsoft document that grants use of System
Center 2012 Endpoint Protection with Azure RemoteApp.
When I first used the gallery template and noticed that Endpoint Protection was installed within it I had the same question as you. I will update this thread if/when I obtain more information.

I'm using prebuild linux_pf, guess its config file is in aur's config.x86_64.
So, I write a utility name as kernel_config_diff.go
http://pastebin.com/YxqEECBE
and run this command will show which config lines which I should append into config.
# yaourt -S gorun
kernel_config_diff.go req.config linux_pf.config
BTW, I don't know is there better solution. I wrote this utility by Google Go because I like it and try to familiar to it.

Well, lxc.config is describe some config file should modify.
But, original config is a long listing.
So, use vimdiff will let you must view long lines of different.
By this script, I could get a quick view.
And even just append the output of this script into kernel config patch.
Here is my sample output compare to different variant kernel config
$ kernel_config_diff.go lxc.config /var/abs/local/linux/config.x86_64
CONFIG_SECURITY_FILE_CAPABILITIES=y

Official Kernel Config [solved]

We sure do have an official kernel config. Any chance for us to have it?
I used to have a custom kernel I made while tampering Gentoo but it is long gone and I'm not in the mood of a Gentoo user.
I need it for zen, anyway.
Edit: Now I realized I already have it on `/proc/config.gz`. Sorry for even posting this.
Edit2: Jason I'm still not in a Gentoo user mood to learn ABS . Thank you for providing yet another thing to tinker on.

[SOLVED] X server and desktop environment?

ok I have 2 Q now I've been studding this quite a long time
well 1. Q
if I want to have a desktop I have to install X server and Desktop environment?
well2. Q
according to this article:
http://en.gentoo-wiki.com/wiki/Intel_GMA
I'd ask do I have to create a new file or is this an old topic for an old X server?
as I have now like this:
/etc/X11/
/twm
system.twmrc
/xinit
xinitrc
xserverrc
/xorg.conf.d
10-evdev.conf
10-monitor.conf
10-quirks.conf

X11 Configuration
If you find yourself needing to tell X11 to use the intel driver, set Driver to "intel" in /etc/X11/xorg.conf as in the example below,
File: /etc/X11/xorg.conf
Section "Device"
Identifier "My Intel Video Card"
Driver "intel"
EndSection
but I don't have it there so... do I need to create a new file or do I get this 4 lines in to
/etc/X11/xorg.conf.d/10-evdev.conf
Depends what works for you. You should do away with xorg.conf, but some setups are easier to pull off with it.
How about creating a new file named 20-intel.conf, just as you do with nvidia?
