I've done some searching, and it looks like symlink is not supported inside a docker container, is there a workaround? I'm also using a volume that mounts to my home directory (on the host), and this is persistent.
When I load the container, existing symlinks in my home directory don't work. I've even tried creating symlinks inside the container, that doesn't work either.
EDIT: I was playing around with mounting >1 volumes, and may have found something. If I mount a volume that mirrors the symlink path, then it seems to work. For example, if I have a data folder that symlinks to /media/disk1 on my /work directory inside the container (and /work is mapped to /home on the host), I can mount another volume that attaches /media/disk1 to /work/data, (and /media/disk1 is symlink to /home/data on the host), then symlink works inside the container!
