Thanks, Paul Smith.  I have not yet, for my system (only as a side
installation, for testing).  Some Linux distributions that matter
for me personally are also waiting, but there are heavyweight
distributions that already switched [1].  Gentoo is critical for
my MUA, as it is source based, and the recipe will fail.  (But
i would not overestimate that problem, i guess very few people are
using the MUA there.)

Thank you very much.  I look forward seeing it in the repository.
