[Unit]
Description=Grow root into the boot drive and create the app-data VG (first boot)
Documentation=https://github.com/dx4homelab/server4home
# Needs udev populated, the root filesystem mounted rw, and LVM tooling available.
# basic.target covers all three; nothing here is boot-critical, so running late
# is correct — a failure must degrade, not hang a headless server.

# The stamp makes this a genuine one-shot across reboots.
ConditionPathExists=!/var/lib/server4home/firstboot-grow.done
# Nothing to grow in a container build.

# Deliberately no Restart=: the script keeps its own attempt marker and refuses
# to retry partition edits unattended. A failure should be looked at, not looped.
