# The catalogue. Nothing in Build/Prepare compiles it, and the RELEASE does not come from luci.mk

# them from nowhere unless this sync makes them. po2lmo is a luci-base host tool, absent from a dev
# machine by default, so this is best-effort: without it the strings stay English and the sync still
# succeeds. (Build it once from the pinned luci checkout: make -C modules/luci-base/src po2lmo —
# plural_formula.c is GENERATED by contrib/lemon, so a bare cc over the .c files cannot work.)
#
# THE BASENAME IS `footstrap-theme`, matching owfeed.yml and NOT the po file's own name: lmo_load_
# catalog globs *.<lang>.lmo so any basename loads, and a v0.8.4 router still owns footstrap.ru.lmo
# through the old luci-i18n package, where the same path would be a file conflict. Sync under a
# different name and the dev router carries two archives for the same msgids, with glob order

# root/ -> / as a TREE, never as a list of names. luci.mk installs root/ wholesale, so a file named
# here one-by-one is a file that ships in the package and silently never reaches the dev router —
# first noticed after a release. The top-level dirs come from a GLOB for the same reason: this used
# to tar `usr` literally, which is a hand-written list of one, and root/etc/ was the counterexample
# already sitting in the tree — root/etc/config/footstrap shipped in the package and never reached
# the router. tar, not `scp -r`, because scp's merge semantics on an existing /usr are ambiguous.
#
# Two subtrees have semantics a blind tar would break, so each is excluded and handled explicitly
# below. Both exclusions are about BEHAVIOUR, not about naming files: a new file under either dir
# still arrives for free.
#   - etc/uci-defaults: deliberately run from /tmp (see below). Landing it in /etc/uci-defaults
#     would make the router's next boot execute it and then DELETE it.
#   - etc/config: conffiles. The package manager does not overwrite them on upgrade (Makefile's
#     conffiles define) and neither may dev-sync — the live file holds the admin's "Save as
#     default", and clobbering it here would be the very wipe that define exists to prevent.
