[Labs-l] [Labs-announce] IMPORTANT: Reboots (again!) on Wednesday

Sun Apr 3 22:23:15 UTC 2016

Is it possible to somehow opt-out of these auto updates and reboots?
Majority of kernel exploits (like 99.9999%) of them can be exploited
only if the hacker has at least some access to remote system (eg. over
ssh) so that they can execute something that eventually get them
rights of user 0.

This makes sense for tool labs, but I see no reason why for example
wm-bot's instance need to get this patch, when all people who can
access it over ssh already have root. I am absolutely sure there is no
security risk while running obsolete kernel on that one for example.
The reboots on other hand cause much more harm.

Thanks
