sysmerge at scale

Hi,

I run a bunch of -current VM and I manage them with ansible. When
there's a file that gets updated in src/etc, I check if it matters for
me and if it doesn't, I ignore it. Then, eventually I sync the file in
my ansible repo with upstream's one. But even then sysmerge keeps
nagging me with:
Subject: example.com rc.sysmerge output

---- /etc/login.conf unhandled, re-run sysmerge to merge the new version

and I usually end up running sysmerge manually with 'd'.

Any advice on how to deal with that? How do you do it?

Cheers,
Daniel
