Bug#987615: perl-base: please ship modules used by usrmerge in perl-base

[Dimitri John Ledkov]

Package: perl-base
Version: 5.30.3-4
Severity: normal

Dear Maintainer,

usrmerge will be needed to be installed upon upgrades to bookworm to
convert systems to merged /usr. It would be helpful for small installs
to be able to perform that without installing the larger perl package.

Please consider moving things that usrmerge & libfile-find-rule-perl
use from per/perl-modules to perl-base.

Specifically please move:

Fatal.pm
File/Find.pm
Tie/RefHash.pm
autodie.pm
autodie/Scope/Guard.pm
autodie/Scope/GuardStack.pm
autodie/Util.pm
if.pm

Once the above is done: libfile-find-rule-perl,
libnumber-compare-perl, libtext-glob-perl would all be able to depend
on just perl-base, and thus usrmerge will be able to just depend on
perl-base too.

In bookworm+1 you may drop these things from perl-base and add breaks
on usrmerge.

Regards,

Dimitri.
