"Permanent" bugs
________________

I consider these "permanent" because I don't know if it's possible
to remove them (1, 2, 3, 5, 6, 7, 8) or I don't think it's worthwile (4).

1) Restoring catalog tar insists to read the whole archive.
   (the catalog is a file in the archive).
   That may be very time consuming for tape so after the reading of catalog
   tar is killed. But because it cannot be stopped at the precise time
   of finnishing, it will write also some garbage. That garbage will be
   deleted automatically from the temp directory you choose but if you have 
   files with the same name then they will be deleted also (from that 
   temporary directory). you can choose a temporary directory for exclusive
   use of cbkp.
   The same applies to afio.

2) Selecting a non empty directory for being restored, tar will restore 
   not only the directory but also it's contents. If the directory is not
   selected but only files from it then the directory will be created
   with some "default" rights.
   Also, selecting a non empty directory and some files from it, tar will
   complain about not finding those files, despite the fact that it will
   restore them all.
   Same for afio.

3) Dialog do not redraw screen so most of functions do not "return"
   but call again the "calling" function.
   This can lead to an overload of a "return" stack if bash works
   like a "regular" compiled language.

4) Catalogs on multivolumes will not be restored (if your catalog is bigger
   than one volume then think seriously to backup on something else).

5) Backup menu will report only the uncompressed size of the archive
   (sum of file sizes).

6) If the root directory path is long then dialog is screwing the screen.

7) On ELF systems "find" doesn't work corectly so you will not see the
   symdirs.

8) For full restore, after a crash, you have to have an up to date
   /etc/passwd and /etc/group for a correct restauration with tar.
