+### Please describe the problem.
+
+Once the assistant daemon is started, it won't notice updates to any gitignore files.  This is probably because it spawns a long-lived `git check-ignore -z --stdin --verbose --non-matching` process which only reads gitignore files on startup.
+
+### What steps will reproduce the problem?
+
+- Start the assistant
+- Add a pattern to a relevant `.gitignore` or `.git/info/exclude`
+- (Just to be safe) wait for the assistant to commit and sync that change
+- Create a file matching the new ignore pattern
+- Observe the assistant committing the file to the repository despite it matching the new ignore pattern

+### What version of git-annex are you using? On what operating system?
+
+7.20191230-gef6d1e327 on openSUSE Leap 15.1
+
+### Please provide any additional information below.
+
+I assume that the obvious fix would be to watch for changes to gitignore files, and restart the `check-ignore` process accordingly.
+
+A workaround is to restart the assistant.  I've tested this and it works fine.
+
+Unsurprisingly the daemon log just shows the normal behaviour so it's probably not very useful, but including anyway just in case:

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+Yes, worked great for many years, but struggling to get the assistant to a point I can use it.  Main blockers are [[assistant_sometimes_removes_and_re-adds_whole_file]] and [[todo/wishlist__58___disable_automatic_commits]].
