Deploy an hourly systemd timer that writes pool and dataset capacity to
node_exporter's textfile collector, since --collector.zfs exposes only
ARC/I-O/state. Add a provisioned 'ZFS - Pools & Datasets' dashboard with
per-pool totals, per-dataset used/quota and daily growth panels.
The archlinux and zfs roles temporarily write `%wheel ALL=(ALL) NOPASSWD: ALL`
to /etc/sudoers so makepkg/paru can run unattended, then restore it in a
following task. Since the restore was a plain sibling task, any failure in
between aborted the play and left the host with passwordless root for the
whole wheel group. Move the restore into `always:` so it runs on failure too,
and narrow the window in yay.yml to just the makepkg call (dependency install,
directory setup and git clone no longer run inside it).
This is not hypothetical: a provisioning run of omega failed on paru's git
clone and left the sudoers hack in place.
The clone failed because the deprecated compile-from-source paru block, which
was commented out in tree, had been re-enabled. It fed paru_git_repo into the
git module, but that variable now holds a GitHub owner/repo slug for the
releases API rather than a clone URL. Remove the block outright, along with
the orphaned paru_src_path default; paru is installed from the release binary.
Also fix the ansible-lint violations this surfaced so roles/archlinux passes
the production profile: explicit `become` next to `become_user`, a pinned
branch on the yay clone, and `changed_when` on the command/shell tasks.
Drop separate dataset-ownership.yml task file. Use
extra_zfs_properties.mountpoint directly instead of zfs get.
Add rmdir cleanup for absent dataset mountpoints.
