I reply to myself. Yes, you can install 'watchdog' on containers and
use it, but you have to take care the fact that load are 'host load'
and there's no a real 'iron' reboot, so container with:
max-load-15 = 12
with a load-15 of 13 reboot, but very probably when they come back, load-15
is still 13. ;-)
I've had a container that do two reboots in a row.
Now i'm testing memory allocation in watchdog (load go high because of
memory exaustion), but indeed with some glitches use of watchdog in
container is doable. ;)
