>Description:
GNU tar in the base system (and the version in ports) seems to ignore the
--one-file-system option. For example, when trying to create a tarball
of the root filesystem, it chokes on /proc (which it should be ignoring):
root@kanga:/# gtar --one-file-system -cf /dev/null /
gtar: Removing leading `/' from member names
gtar: /proc: Cannot savedir: Invalid argument
gtar: Error exit delayed from previous errors
root@kanga:/#
bsdtar, on the other hand, works as expected:
root@kanga:/# tar --one-file-system -cf /dev/null /
tar: Removing leading '/' from member names
root@kanga:/#
This is relatively recent behavior. I had been using a 5.2.1-era system
until a few weeks ago, and only discovered this behavior after I updated
to 5.3-RC4 (and later) and my nightly Amanda backups began to fail.
>How-To-Repeat:
Attempt to create a tarball of a directory containing a mountpoint for a
proc filesystem.
