... when it's broken.. Bleh.
Somehow, three of my libraries and a lot of System Frameworks got zeroed out. (Tip: when that dialog comes up warning you of your almost full hard drive, do something about it.) Usually I'd just grab an OSX install dvd, do the brilliant Archive and Install and be done in 15 minutes. But of course the thing is nowhere to be found. So I had to fix it The Hard Way.
Scp stopped working because Kerberos was hosed, but luckily ftp did still work (even though libresolv was out, too). So I tediously ftped over a few files from another box such that scp would work again (the paths to the Frameworks are very long). After that I could copy over the rest with scp (with $(pwd) and proper tabbing available) for a couple of hours. Ugh. Some of my applications are still b0rked.
