+The native TAPM host configuration workflow replaces the former ProxMenux
+post-install dependency. It can audit a host, apply the recommended PVE 9
+profile, customize individual items, migrate recognized ProxMenux
+configurations, repair ProxMenux's system gzip replacement, and remove
+ProxMenux after validation. Every mutating run first creates a timestamped
+backup under `/var/backups/ta-proxmenu/post-install`.

+compatibility check is optional. Global vzdump bandwidth and I/O-priority
