>Description:

On a system with ptyfs mounted on /dev/pts, try to update from the base set
after I added /dev/pts to the set:

# stat /dev/pts 
31489 2 dr-xr-xr-x 2 root wheel 0 512 "Nov 23 20:34:49 2020" "Nov 23 18:39:49 2020" "Nov 23 20:34:50 2020" "Nov 23 13:18:38 2020" 4096 1 0 /dev/pts
# tar tvzf /mnt/sets/base.tgz ./dev/pts
drwxr-xr-x  0 root   wheel       0 Nov 23 18:39 ./dev/pts

.. so it should be a no-op. However, a "tar xpzf base.tgz" complains:

./dev/pts: Can't set user=0/group=0 for dev/pts
tar: Error exit delayed from previous errors.


>How-To-Repeat:
s/a

>Fix:
Make tar skip this kind of "error" silently?
