I'm running docker with a host directory mounted:
$ docker run -v /usr/groups/thing -ti imagename /bin/bash
Files in /usr/groups/thing/foo
are accessible:
# ls /usr/groups/thing/foo
a b c
But files in /usr/groups/thing/bar
are not:
# ls /usr/groups/thing/bar
ls: cannot open directory /usr/groups/thing/bar: Too many levels of symbolic links
This is on Debian, and /usr/groups/thing
is an automounted NFS volume.
