[gentoo-user] custom mount fstab

[gentoo-user] custom mount fstab

[Tamer Higazi]

Hi people,

I had a problem with docker on gentoo and found the solution for all my 
problems with a custom mount command:

|sudo mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd 
Can anybody of you tell me how to add that one in /etc/fstab file ?

I haven't used cgroups or docker, but if your mount command above is correct, 
I assume something like this ought to work as far as fstab is concerned:

cgroup  /sys/fs/cgroup/systemd  cgroup  none,name=systemd  0 1

Thanks Michael!

I'll give it a try.

Hi,

Not sure if this may help but there is a library which you can install
called dev-libs/libcgroup which has an init program /etc/init.d/cgconfig

In the config file /etc/cgroup/cgconfig I have 

mount {
    "name=systemd" = /sys/fs/cgroup/systemd;
}

which allows lxd containers to run using systemd


Not sure if this what you are after but maybe of use. It allows me to
run Arch linux containers in Gentoo.

Docker on OpenRC or systemd?

Also with the new cgroups or old?

AFAIK Docker doesn't work or support the new cgroups. :/

Hi Andrew,

it's on systemd.

Previously I had problems connecting with docker.
After I searched on Github, docker ran then without any problems at all.

I use docker and I don't have to add anything like that to fstab. 
systemd mounts it automatically. However:

https://wiki.gentoo.org/wiki/Docker#Docker_service_fails_because_cgroup_device_not_mounted_.28systemd.29

So make sure to emerge systemd with the "cgroup-hybrid" USE flag set.
