Odi's astoundingly incomplete notes
New entries | CodeOn Gentoo sshd is killed after udev is triggered
After running some updates I noticed that sshd (including active sessions) were somehow killed sometimes. After much debugging I found the reason: udev and cgroups. It looks like udev can send kill signals to all members of its cgroup if it thinks that it's a systemd system. But on OpenRC systems that just does a lot of harm.
That udev triggering happens for example during:
Note the absent udev directory under
This also explains why the problem is fixed by a reboot.
I have filed a bug against OpenRC.
That udev triggering happens for example during:
- grub-install
- startup of qemu with kvm
/etc/init.d/udev -D restart. The culplrit being the -D flag. The flag causes cgroups to be not set. So udev ends up in the main cgroup!Note the absent udev directory under
/sys/fs/cgroup/openrcThis also explains why the problem is fixed by a reboot.
