Hello,

the attached script parses your hdup.conf and writes a file out
with a the directory info it can find. The script can be used=20
so fill the caps the current hdup2/gnu tar combinations leaves.
(also see some earlier mails on that).

The information is stored in your archive directory in
<host>/<date>/<date>.dirinfo and all entries are like this:

755|root|root|/var/var/www

(see man find - look under printf)

The script isn't tested much, only developed under Linux and used
some bash3.0 structures (the regular expressions). And it uses Gnu
find to do the hard stuff....
Appart from that, it seems to do the trick.

I'm planning to take a loooong vacation this year and in that time I
hope to work on patching tar and hdup2 and release a 2.0.8 version.
This is gonna be sometime in july, until that time  I welcome any
patches and comments on this script (it's going to be included
anyhow).

Oh, a dirinfo restore functionality isn't hard to add I guess. Using
this script as a post-run during backups/restore makes the whole
thing pretty transparent I guess,
