Hi,
I'll try to avoid pushing a huge review'n'merge request about
incremental updates at the last minute before the 0.22 freeze, so here
we go for a first batch.
feature/perl5lib extracts some code from t-p-s into a new package
called tails-perl5lib, that provides Perl libraries that other
Tails-specific code may want to use. This refactoring was needed to
make tails-iuk (incremental updates software) share code with t-p-s.
Candidate for 0.22, no ticket.
Branches:
  * t-p-s feature/extract-code-to-perllib
  * Tails feature/perl5lib
  * an APT suite to merge
Note that the t-p-s branch also contains Andres fixes for the
persistent volume deletion warning (#5888), and it also supersedes my
review'n'merge request for bugfix/persistence-cleanups. This is on
purpose, so that we'll save a review'n'merge pass or two.
Cheers,
--
