 This assumes you know what `srcdir`, `repository` and so on mean, if you forgot (like me), see this reference: [[rcs/git/]].

 What doesn't work
 -----------------
 
-With a recent version of git-annex: mostly everything. :) Since git-annex in `direct` mode now [sets the repository as bare](http://git-annex.branchable.com/devblog/day_48__direct_mode_guard_design/), *nothing* gets committed at all.
-
-What would need to happen in ikiwiki would be to detect that `$srcdir` is running git-annex in direct mode and then do some magic. Here is a tentative incantation in shell:
-
-    if [ $(git config core.bare) == 'true' ] &&
-       [ $(git config annex.direct) == 'true' ]; then
-        git annex add --auto
-        git -c core.bare=false commit -m'testing git-annex with ikiwiki'
-    fi
-
-This probably needs to happen around line 571 of `git.pm` or, more likely, in a new `git-annex` plugin.
+ * the above plugin is kind of flaky and ugly.
+ * it's not an RCS plugin, but probably should be, replacing the git plugin, because really: git doesn't work at all anymore at this point
 
 What remains to be clarified
