Backed everything up to CD/Server, swapped out the 128MB RAM stick with a 512M RAM stick bringing my total to 640M, and zeroed the HD. Totally wiped it clean.
Reinstalled the OS, set all the settings.... realized I forgot to save all my network settings (lost my work profile, gonna have to set that up again). That's all I lost. Everything else I backed up restored smoothly. TBird took all my email from before, AddressBook took all my AIM contact names and kept all the custom fields, Palm Desktop works and even synchs with my palm, Firefox imported bookmarks smoothly, VPC installed without a hitch and took my VMachine profiles, and iTunes didn't chow on the library like I've had problems with before. Even Keychain didn't give me many problems.
Switched my default shell from Bash (teh suck) to ZSH (teh w00t).... that took some googling, since MacOS wanted to dump me back into Bash every time I opened a new Terminal window.
Got most of the Mac-side applications installed, there's still a few UNIX apps I need to compile/install, then reload all my non-essential documents, pictures, porn, videos, games, etc.
I'm thinking I had about 7GB of preference files, remnants from old programs, font extras I didn't need, and other miscellaneous bullshit that had collected over 2 years that I finally scrubbed off this computer. I deleted everything I backed up, and even with all my shit backed up I still had about 10GB I couldn't free up, and after clean-installing the OS there was only 2.5GB used.
And a good, complete, up-to-date backup is a nice thing to have too :smokin:
