# ---------
# Safely update to the latest LineageOS build/kernel and re-apply the Droidspaces
# namespace config (and KernelSU-Next).
#
# Run from the LineageOS source root. This script itself is fine to run from fish.
# After it finishes, the build step still needs bash:
#   bash; ulimit -v unlimited; source build/envsetup.sh; brunch diting
#
# It discards our local kernel edits FIRST so `repo sync` is conflict-free, pulls the
# latest, then re-applies everything cleanly via apply-droidspaces.sh.
