For homedirs

Dump it to a disk image/CD, then copy it back, overwrite everything.

The biggest problems happen if your new UID is different from your old UID.
But chown -R fixes that.

For /Library, the best way is a clean install that preserves user and
network settings. There's *maybe* a handful of things that won't get put
correctly for you, and they'll be sitting in the same relative place in the
/Previous Systems/ directory.

For /System, leave it the heck alone. If you had kext's in there, just
reinstall from source media.
