selinux and mounted partitions

[Thomas Molina <tmolina cablespeed com>]

I have my system set up for testing and easy swap between setups.  I put 
the root partition on one ide drive (/dev/hda) and /home and /usr/local on 
a second ide drive (/dev/hdd).  /dev/hda is in a removable caddy, allowing 
me to swap in a known stable setup or change between several test setups.  

How possible is it that I will run into trouble when I install an 
selinux-enabled setup, swap out to my stable caddy, and then swap back in 
the selinux setup?  If so, what could I do to minimize the problems?

Thanks.
