Comment 58 for bug 934291

@ken-vandine: I'd not name the system user 'lpadmin' but rather 'cups-pk-helper', which is more precise, especially as its creation/deletion is handled by the cups-pk-helper maintainer scripts.

Other than that, it looks like a good solution.

That said, only the cups-pk-helper maintainer in Debian (Guido Günther, see https://tracker.debian.org/pkg/cups-pk-helper) can have a definitive opinion there.
