A - fairly hacky, but keeps your home in /Users, and on another partition. add a startupitem that unmounts the partition from its default spot, and remounts it at /Users/catscout.
First, to get the device name, run df.
In my case, there is a line like this:
Renaming the partitions so that they start with a dot [.] vill hide them in finder, untill they are activated. If you move to your home filder that partition will show up in finder, but as a greyed disc. Also your mount point will show up as symbolic links not as the folders they are.
Uh. I used to have a partition on a 2nd drive, and it was called ".Swap"
It NEVER showed up in the finder. You know why? Cus files starting with "." are hidden. And so, the finder doesn't show them. And as for moving your home directory. I simply changed the location of my home directory in the NetInfo database, and then copied my /Users/accountname stuff to the partition, and logged out and back in. SIMPLE.
I've had similar issues with my imac, you can only have the os with in the first 8 gigs so i have a 7.9 GB partition for the os and a 23 GB partition that i use (trying to use) for my downloads and mp3's and stuff, but when i save something to that partition or choose it as a download folder in direct connect or limewire it's not there it's under HD/volumes, kinda annoying.?
