git annex init probes for crippled filesystems, and sets direct mode, as well as `annex.crippledfilesystem`. Avoid manipulating permissions of files on crippled filesystems. That would likely cause an exception to be thrown. Very basic support in Command.Add for cripped filesystems; avoids the lock down entirely since doing it needs both permissions and hard links. Will make this better soon.
