Instead of my custom-baked implementation, that doesn't support
file system ACLs and is quite slow, we switch to `fuidshift` from the
`lxd-tools` Debian package.
I previously thought that handling symlinks would not be necessary and
also not possible. Then, I found out about the `--no-dereference` option
for `chown` ...
I've used this script to remap files' uids/gids of containers created
without a custom userns into their new range. It's inferior to
`fuidshift` from the `lxc` project in that it doesn't handle ACLs and is
quite slow - probably because it calls a binary for every file.
By default, it runs in debug mode only printing the chown command
instead of executing it. You need to edit the file to use it.
It also only works with LVs (logical volumes from LVM), mounting them
automatically.
