Důvod: Aktualizace OS
Odstávku řeší: Jakub Skokan, Richard Marko

Budeme aktualizovat kernel na 5.1.15 a LXC na 3.0.4. Kernel máme upraven tak, aby bylo možné ve VPS nastavovat oom_score_adj pro vybrané procesy. Hodí se to např. k ochraně kritických služeb jako sshd před OOM killerem.

We'll be updating kernel to 5.1.15 and LXC to 3.0.4. The kernel is modified to allow VPS to set oom_score_adj of selected processes. This is useful to prevent critical services such as sshd from being killed by the OOM killer.
