Mounting USB key in %post script

[Alex Tang]

Hi folks.

I've been reading the threads about booting and installing from 
kickstarts on USB Keys, however, i'm trying to mount a USB key in a 
%post script (in the chroot environment).  I can't seem to get it to 
work.  Is this possible? What parameters to mount should I use?  How do 
i figure out what device i should be mounting?

thanks.
