I released git-annex an unprecidented two times yesterday, because just
after the first release, I learned of a another zombie problem. Turns out
this zombie had existed for a while, but it was masked by zombie reaping
code that I removed recently, after fixing most of the other zombie
problems. This one, though, is not directly caused by git-annex. When rsync
runs ssh, it seems to run two copies, and one is left unwaited on as a
zombie. Oddly, this only happens when rsync's stdout is piped into
git-annex, for progress bar handling. I have not source-dived rsync's code
to get to the bottom of this, but I put in a workaround.
I did get to the bottom of yesterday's runaway dbus library. Got lucky and
found the cause of the memory leak in that library on the first try, which
is nice since each try involved logging out of X. I've been corresponding
with its author, and a fix will be available soon, and then git-annex will
need some changes to handle dbus reconnection.

For the first time, I'm starting to use the assistant on my own personal
git-annex repo. The preferred content and group settings let me configure it
use the complex system of partial syncing I need. For example, I have this
configured for my sound files, keeping new podcasts on a server until they land
somewhere near me. And keeping any sound files that I've manually put on my
laptop, and syncing new podcasts, but not other stuff.
# (for my server)
preferred-content 87e06c7a-7388-11e0-ba07-03cdf300bd87 = include=podcasts/* and (not copies=nearjoey:1)
# (for my laptop)
preferred-content 0c443de8-e644-11df-acbf-f7cd7ca6210d = exclude=*/out/* and (in=here or (include=podcasts/*))
Found and fixed a bug in the preferred content matching code, where
if the assistant was run in a subdirectory of the repo, it failed to
match files correctly.
