I recently tested tar to see if the behavior of tar clobbering a
pre-existing archive whenever a verifying append or concatenate is
attempted and the same old behavior still exists. Here is a script that
can be ran locally to get the kind of behavior I'm seeing:
====================BEGIN SCRIPT====================
#!/bin/bash
## Setup our directory structures, ADir and AnotherDir
mkdir -p Adir/Subdir{1,2}
for directory in `find Adir/ -type d` ; do touch $directory/file{1,2} ; done
mkdir -p AnotherDir/Subdir{3,4}
for directory in `find AnotherDir/ -type d` ; do touch
$directory/file{3,4} ; done
## now make a superCoolArchive to stuff ADir in
tar -c -W -f superCoolArchive.tar ADir
## wait, I want AnotherDir in the superCoolArchive too, so...
tar -r -W -f superCoolArchive.tar AnotherDir/
## now to go see what our superCoolArchive has in it...HAY, WHERE'S THE
## STUFF FROM ADir?!
tar -t -f superCoolArchive.tar
====================END SCRIPT======================

I'm sorry for not doing this check earlier. I only recently
discovered that this bug was marked as fixed (never got an email from
the Debian bug tracking system). Thanks for your help.
