# now the archive has everything in it, and is about 100MiB. Strip it
# to just en_US (basically, this is the locale we support if you ssh
# in, other than POSIX)

$(localedef --list-archive | grep -v '^en_US' | xargs)
# This removes the locales from the archive index but doesn't rebuild
# the file, so it is still the same size (maybe it is sparse?
# presumably as it's mmapped you don't want to fiddle with the offsets
# of locales in the archive on a live system. We are not live).
# build-locale-archive is a tool provided by the RH packaging of
# glibc. Documentation is scarce, but it takes the pre-built locales
# in the tmpl file and creates an archive. It seems originally the
# installer would set some flags to rpm to tell the package what
# languages to pick out of the template, but along the way, this was
# reverted to install them (size considered less important than locale
# support).
# We hack this by moving the locale-archive we've removed the extra
# locales from to the template, then re-run the build.

# leave empty template behind as package does. I think this stops
# upgrades redoing things
