Switch to aufs-friendly kernel

Hey,

I'm just installing docker on arch linux using yaourt, as recommended here: http://docs.docker.io/en/latest/installation/archlinux/.

One of the final steps is to tell my bootloader, in my case grub, to use the aufs-friendly kernel. I don't know how to do this, and I'm scared I will make a horrible mess of it. I've been reading the grub documentation, and also found this potentially useful advice http://unix.stackexchange.com/questions … -archlinux.

However, I would love some help to save me doing something stupid. Hope you can understand.

I use Cario Dock, works flawless, at least on my rolling release with KDE.  I suggest this because what you are tying to do is not available but I will be glad to show you how to run grub commands.

What you are looking for is in the grub file itself.

sudo nano /etc/default/grub
Find the line:
GRUB_CMDLINE_LINUX=""

change to:
GRUB_CMDLINE_LINUX="your_parameter_here"

replace "your_parameter_here" with what you want to load, include quotes.

contro x to exit, don't forget to save.

Then run: sudo grub-mkconfig -o /boot/grub/grub.cfg

As far as aufs goes, seems to be a no go as it is Flagged out-of-date (2013-09-19) so I do not know what alternatives you have other than to use another dock program like I did.

Re: Switch to aufs-friendly kernel

The Docker program that he's looking for isn't a window manager docker - its a devops tool that just came out.  Easy to confuse them though.

One place to find the GRUB rebuild command is here:

https://wiki.archlinux.org/index.php/Linux-ck

It says this:

Note: As with *any* additional kernel, users will need to manually edit their boot loader's config file to make it aware of the new kernel images. For example, users of GRUB should execute "grub-mkconfig -o /boot/grub/grub.cfg". Syslinux, GRUB-legacy, etc. will need to be modified as well.

Once you reboot you'll have an option to boot the AUFS patched kernel, your stock kernel will be there as an option too.
