I don't think so. Well, you could write a shell script to re-install everything automatically ;) > So, let's say, is it possible to backup some directories and files via > ssh, flash the device, reinstall the ssh server and write the backed up > stuff into the flashed device, in order to have everything working again > with minimum effort? 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) > If yes, can someone write a list of the dirs/files to > include (or exclude) in the backup in order to accomplish this task?

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?
