Would it be very hard to allow perpetual postinstall scripts to run either
before or after all others? The names could end in _always_before or
_always_after to indicate which type of script it is. It seems unnecessarily
limiting to assume that all perpetual postinstall scripts should run before all
I could make very good use of this for improving the texlive postinstall process.
