ok, it is the extracting that’s the issue here, the localedef call is
not fast, but does not exceed any resources.
So, can’t locales-all just ship /usr/lib/locale/locale-archive
completely?
Alternatively, the load on /tmp could be reduced considerably by
something like this in postinst (untested pseudocode):
if [ "$1" = "configure" ]; then
[ -d /usr/lib/locale ] || mkdir /usr/lib/locale
# Remove existing locales, otherwise localedef does not
# overwrite them and exits with a non-null value
rm -f /usr/lib/locale/locale-archive 2>/dev/null || true
tmpdir=$(mktemp -d -t locales.XXXXXXXXXX)
trap 'rm -rf "$tmpdir" > /dev/null 2>&1' exit
for locale in list of locales filled here at compile time
do
tar --use-compress-program /usr/bin/lzma -xf /usr/lib/locales-all/supported.tar.lzma -C "$tmpdir" ./$locale
localedef --quiet --add-to-archive "$tmpdir"/$locale
rm -rf "$tmpdir"/$locale
done
fi
(list of locales could also be read by
tar --use-compress-program /usr/bin/lzma -t -f /usr/lib/locales-all/supported.tar.lzma | cut -d/ -f2|uniq
if putting it there at package compile time is troublesome).
Greetings,
Joachim
