I'm backing up `/storage/netfiles/testfolder` and the repo directory
is located in `/root/repo`
I'm mounting to `/tmp/testRepo` using the following command `borg
mount ./repo::filesrv1_2-23-2022 /tmp/testRepo`

I want all xattrs and acls backed up, so none of these options are
included in my backup command (listed below)
(   eval $(ssh-agent) > /dev/null;   ssh-add -q
~/.ssh/borg-client_key; ssh -A -o StrictHostKeyChecking=no
root at filesrv1 "borg --rsh 'ssh -o StrictHostKeyChecking=no' create
--list ssh://root@borg-test/~/repo::filesrv1
_2-23-2022 /storage/netfiles/testfolder";   kill "${SSH_AGENT_PID}"; )

Note the above command is not exactly what's on the docs linked, as
that is from my most recent attempt, being without encryption.

All systems we're backing up have acl support, they are all running
Ubuntu and if it's not explicitly set in the mounting options, it's
mounted with ACLs by default as modern Ubuntu does now.

No, the first try I did was using the default version in the ubuntu
repos, which was 1.1.11, and I was seeing the same issue.

I just gave it a shot on push mode, and both mount and extract show
the same issue.
