tar: incremenatal backup

[Niels Laukens]

Hello,

I'm not sure if this is a bug, it could be that I don't fully understand
the manual.
I tried to do the following: make a full backup of a directory tree.
Change some files, make an incremental (level 1). Delete the tree an try
to restore:
[ directory tree is under 'test' ]

tar cvf full.tar --listed-incremental list.lst test
rm test/some.file
tar cvf incr.tar --listed-incremental list.lst test
rm -r test

tar xvf full.tar --listed-incremental list.lst

Here, tar doesn't extract the test-tree, but extracts dirs like
07713157175/test/...
I tried extracting without the incremental option, with --incremental,
and with --listed-incremental list.lst; none of them gave the desired
result...

Any advice/bugfix/explanation/blames?

Thanks in advance,
Niels
