Joshua Boniface 07d75573d6 Add updated tuning configuration
Uses a much nicer CPU tuning configuration, leveraging systemd's
AllowedCPUs and CPUAffinity options within a set of slices (some
default, some custom).

Configuration is also greatly simplified versus the previous
implementation, simply asking for a number of CPUS for both the system
and OSDs, and calculating everything else that is required.

Also switches (back) to the v2 unified cgroup hierarchy by default as
required by the systemd AllowedCPUs directive.

Joshua Boniface 1d35fec8a8 Remove cpuset configurations
This functionality simply did not work, with Libvirt continuing to dump
its processes into the root cset thus defeating the purpose entirely.

Just remove it, from some very initial testing it isn't worth the
headache.

Joshua Boniface 30ddeb0fee Update MOTD automatically on boot
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.

Add model and serial numbers to the vendor, and put this on its own
line. Also use BASH for proper syntax formatting. Reformat the header to
be a more compact format.

Joshua Boniface e8fe165e00 Further optimize ownership agent output 2023-09-01 15:42:28 -04:00
Joshua Boniface cbea6e284c Make ownership check consistent with cmk-agent 2.1
The new CheckMK agent uses UID 998 (dynamic) for itself. This causes
ownership problems with the old logic of this check. Move instead to a
range, where the UIDs from 200-599 are reserved for administrators, and
check for this range explicitly. Also eliminates the exceptions for ceph
and 2000 from previous iterations.
