Re: Problem with --listed-incremental option

[Neologism]

I'm having the same problem with tar 1.13.19.  Is listed-incremental
broken?

Hi,

I'm assuming I don't understand how the tar command works with
the -listed-incremental option.  I am assuming that if I had a directory A
with files 1, 2, and 3 in them and I did a level 0 dump like this with tar:

tar -create -verbose -file=dump0.tar -listed-incremental=inc.info A

then doing an incremental right after it like this would do nothing really:

tar -create -verbose -file=dump1.tar -listed-incremental=inc.info A

Although I do get 2 tar files.  After making the first tar, inc.info has
very little information in it (looks like 1 number to me).  I expected all
files and some human readable information here.

The second tar seems to just backup everything again in dump1.tar.  I would
have expected modifications to the inc.info file.

I must be doing something wrong here.  Perhaps you could set me straight.  I
can get you the version numbers of tar, but I was using the one with RedHat
7.2 so it should be rather recent and I didn't see any blood in the streets
about this problem on the web.

Thanks!
