Arch on a server is a tricky thing, of course creating a viable long term
infrastructure architecture is also a tricky thing, the problem is that MANY
sys admins adhere to the idea from the 80s, that you set up a server once
and then leave it be for years on end. This is no longer possible, and this
idea about system management is not only outdated, but very dangerous.
So a viable infrastructure requires %100 failover capacity for all services,
so that reboots are routine, and never dangerous, in my deployments we
reboot systems VERY frequently, often not even into new kernels, but just to
continually verify the failover viability.

As for a home server, I generally set up a cron job on those to do a pacman
-Syu every night, detect if the kernel has changed, and then reboot
automatically. No problems with it so for (This is also how my main company
build servers work)
