After install LTS kernel I cannot boot. I get the error:

systemd: Failed to mount cgroup at /sys/fs/cgroup/systemd.

I have find a bug related in arch systemd but it seems solved in systemd 213.

Any ideas?.

Confirmed, will look into this, see what is needed for linux 3.2 to still work with systemd 214.

You kept the regular kernel, so you can still boot?

There is no clear cut solution for this, need the opinion of other KaOS users what will be the best way to proceed.

In the meantime there is a solution for you if you need the lts kernel now. Systemd-lts is up in build, you can install it with:

sudo pacman -U http://kaosx.us/repo/build/systemd-lts-212-1-x86_64.pkg.tar.xz

Answer "yes" to the replace question.

I have other kernel installed.

Thanks.
