Trying to add new /tmp partition to machine. btrfs error?

SUSE Linux Enterprise Server SLES Configure-Administer

I’m getting the following if I add a drive to sles12sp2 machine and try to mount it on /tmp

Warning: Some subvolumes of the root filesystem are shadowed by mount points
of other filesystem. This could lead to problems.

@/tmp

Really use this setup?

Is there a way to tell btrfs not to shadow /tmp? Or is something else going on?

Thanks,
Matt

Hhmm… looks like the only option that is working for me to remove the subvolume is to use yast, and ignore the command line. Not sure why I can’t figure out the right path.
