PVE refuses a restore carrying mountpoint params unless rootfs is also set ("mount
points configured, but 'rootfs' not set"). Size the rootfs override from the source
rootfs (rootfsSizeGB/sizeToGB, round up). Validated manually on the host: restore of
bind-mounted 9201 with --rootfs + --mp0/--mp9 overrides boots + tears down cleanly.
