Public bug reported:
Binary package hint: libecryptfs0
The problem shows up in Git, though I don't think it is a Git problem
(though I could be wrong). The issue is that when Git tries to read a
symlink on an eCryptfs filesystem, it fails with:
error: readlink("link-to-file"): Invalid argument
error: unable to index file link-to-file
I can confirm that it works on my ext4 root partition, and it has worked
in the past, so I'm fairly sure it is an eCryptfs issue.
I have attached a script which demonstrates the problem. It creates a
folder "test" in the current directory, initiates a git repository, adds
a file and a link to that file. Here is what the output looks like for
me:
(/ is an ext4 partition and my home folder is eCryptfs)
$ cd /tmp
$ sh ~/test-script.sh
Initialized empty Git repository in /tmp/test/.git/
