Public bug reported:
Hello
In a 22.04 version installed in an EXT4 partition, I am trying to watch the
contents of a 22.04 version installed in a ZFS partition.
I can't. However, I can easily access the "duplicate" of this partition which
was created under ZFS.
I think it certainly needs an additional option that I can't find. But maybe
this is a bug???
Can you help me. Thank you.
