This should be somehow a uncommon thing but i wanted to get notice. I sync my
tofu.d directory with git annex. Removed the .git directory in that place lead a
lot of symbolic link not find the original file, as expected, but when trying to
open a mail from mutt i was not able to see them and the keys were not recreated
as the .git directory wasn't there
