i recommend clean install. it is also possible to move home directory to different location, but some application may insist home directory be under users directory. Taz Mangus approach is good but doing so is dangerous. i take no responsibility if something goes wrong with your system. use it at your own risk. first answer few question and proceed further.
do you show hardisk(s) on your desktop?
are you okay with having additional "Users" hd icon on your desktop?
are okay with your system logs being full? (4000 console messages very quickly)
if "yes" then follow little guide below read it once completely and see how process works before implementing it directly.
so here it goes
when your installing your system, install OS X on SSD drive. format HDD and name it "Users". let install finish and on very first restart hold down shift key to boot into safe boot (safe boot prevent creation of dyld cache). create admin user in safe boot and enable root user via "Directory Utilty" located at /System/Library/CoreServices/Directory Utility. log out and log into root user, fire up "Terminal" and move User directory with following command
now create new "Users" directory and give proper (super) permissions to it by entering following commands one line at a time in "Terminal"
now open "Disk Utility" and get UUID of "Users" partition (press command + I)
note down UUID.. and unmount "Users" partition. leave "Disk Utility" Open and type following in "Terminal" one line at time
Create & backup "fstab"
Code:
touch /etc/fstab && cp /etc/fstab /etc/fstab.bkp
Now time to edit "fstab" in textedit
Code:
open -a TextEdit /etc/fstab
New blank textedit window will pop up, in that insert following
UUID=$ /Users hfs rw,auto
where $ = UUID that you noted down earlier for "Disk Utilty"
save filer and quit textedit.
back to "Disk Utility" and mount "Users" partition also enable ownership with following command in "Terminal" though not necessary.
Code:
diskutil enableOwnership /Users
now move your users to new location with following in "Terminal"
Code:
mv /UsersOld/* /UsersOld/.[^.]* /Users/
copies with all resources.
finally delete old "Users" directory with following in "Terminal"
reboot and verify that it had mounted properly. apply any combo and system updates and enjoy
hope this helps
Note: you can rename "User" partition to whatever you want but only do it after moving users to new partition. also enable "noatime" for SSD.
