I don't think so.
Well, you could write a shell script to re-install everything
automatically ;)

That's more or less what I did when I upgraded from OS2005 to OS2006,
and that's what I plan to do to upgrade to OS2006.2:
- create a backup with the backup tool
- back up some files in my home directory (a simple shell script that
tars things like ~/.profile and my ~/mmc -> /media/mmc1 symlink into
the memory card)
- flash
- restore the backup
- install osso-xterm, becomeroot and ssh
- untar my home dir archive (another shell script that untars the
archive)

I think that using tar to back up and restore applications installed
with apt/dpkg would be a Bad Idea.
It should be pretty easy to get a list of installed packages from apt
(or the application installer) before the flash, and then reinstall them
in one swoop with apt-get install. I plan to figure this out over the
weekend.
By the way, can someone confirm or deny that the backup tool does not
back up your /etc/apt/sources.list and therefore you will have to re-add
all the application manager repositories manually?
