Does anyone know of a Linux tar that doesn't behave like the above? I think you're misreading his intent. He wants *only* the dotfiles (and none of the regular files), so what he wants is tar zcf dotfiles.tar .* However, when you ask for .*, the expansion includes . so your entire home directory is tarred up in the tarball. He should change it to tar zcf dotfiles.tar .?* which will require at least an additional character. But when you do this, .. is included in the glob expansion, and so .. and all its children get included in the tarball. (Yes, I tested on GNU tar) That's why he changed it to the following, which requires there be a non-dot character after the dot tar zcfv dotfiles.tar .[!.]* ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

It got through all of the pkgs in the Upgrade step (next step being Cleanup) and complained that some stuff wasn't installed, and it would issue a dpkg-reconfigure -a or somesuch to fix itself. Dimissed that window, then the main window hung (blank). It's late, and it looked in a bad state, so I zapped it and rebooted.
