Well update of my rawhide usually more then 3/4 hour - so 6 minutes running in
background - that's really nothing.

And quite frankly - during the update you need to update/recompile only
changed files - you could copy compiled & unchanged data to new file - thus in
fact it would takes couple seconds - unless each glibc update changes all i18n
locale definition, I doubt that - isn't that what the locale-archive.tmpl is
already doing?

(And as a bonus you save package size as you don't need to store tmpl inside)
