[pmg-devel] [PATCH pmg-api v2 0/2] sa-custom: move shadow config next to live config

[Stoiko Ivanov]

supersedes: https://lore.proxmox.com/pmg-devel/7d32a0e7-083e-4c2d-bcca-0dd55e0ec5cc@proxmox.com/T/#t
changes v1->v2:
* following Thomas' and Dominik's feedback simply moved the shadow file to
  the same directory as the live one (after checking what SA does when
  parsing its config) - Thanks for the suggestion!
* patch 2/2 moves the file upon package installation.

original cover-letter for v1:
the custom scores are kept in /var/cache/pmg-scores.cf, until they are
applied, by moving them to /etc/mail/spamassassin/pmg-scores.cf.
This currently happens with perl's `rename` function [0], which is a
wrapper for rename(2). `rename` does not work across filesystem
boundaries (errors out with EXDEV).

having `/var` on another filesystem is becoming less common, but
should probably be supported.

following the recommendation of [0] switch over to `File::Copy::move`,
and add some error-checking. File::Copy is shipped with
perl-modules-5.36, thus it does not introduce a new dependency

reported in our community-forum:
https://forum.proxmox.com/threads/.154814/

tested in a container with a seperate volume for `/var/cache`.

other occurences of `rename` in the repo should not be affected
(moving files within the same directory, or e.g. from /etc/pmg/master
to /etc/pmg).
