[Bug-tar] Modifying Volume Label with tar.

[Ralph Corderoy]

Hi,

After creating a tar file with a volume label, `tar -V everything -cf
foo.tar .', I can use --delete to remove items, e.g. to create a delta
against an earlier tar file, but how do I modify the volume label to
reflect the tar file no longer contains everything?

Doing `--delete -V something' doesn't work because tar takes that to
mean `check the existing volume label matches the one given'.

I can create a second tar file, `tar -V something -cf bar.tar
dummyfile', and then append foo.tar, with -A, to bar.tar but that
results in two volume labels.  Does this matter or will tar only ever
think of a volume label that appears as the first item as the real one?

And is there any way to create a tar file with nothing but the volume
label, i.e. remove the need for dummyfile above?

Thanks,


Ralph.
