[pve-devel] [PATCH pve-manager v2 3/4] api: add service state return schema

[n.frey@proxmox.com]

From: Nicolas Frey <n.frey@proxmox.com>

values for the respective states (active-state, state, unit-state)
were taken from the systemd manpages [0] for ActiveState, SubState,
and UnitFileState. With the addition of unknown and not-found to
account for logic present in the code.

[0] https://manpages.debian.org/trixie/systemd/org.freedesktop.systemd1.5.en.html
