# dev-setup.sh — run INSIDE the NoSignal dev VM to point the running shell at
# this fork checkout (shared in over 9p), so host-side QML edits preview live.
#
# Prereq (run once per boot, needs root for the 9p mount):
#   sudo mkdir -p /mnt/fork
#   sudo mount -t 9p -o trans=virtio,version=9p2000.L,access=any nsfork /mnt/fork
#
# Then:  sh /mnt/fork/packaging/dev-setup.sh   (then Ctrl+Super+Alt+R to load it)
#
# Quickshell resolves `-c caelestia` from ~/.config/quickshell/caelestia BEFORE
# /etc/xdg/quickshell/caelestia, so this symlink makes the session shell read
# the fork. The compiled Caelestia plugin still comes from the installed package
# (Qt qml import path), so only the layout QML is sourced from the fork.
