Hi folks, this is me again, the one who "upgraded" from a "not-so-experienced"
Unix user to "Beginner-SysAdm." So here are some new dumb questions to
bother you guys again.

1. When mount an OD on multiple disk system,  ALL files on the OD
   belong to the person who mounted the OD.  Does this mean if some one takes
   my system disk and mount it in his/her/public cube, he or she can perform
   ALL kind operations to the files on my OD even like change root privilege
   of my files?
2. If I build my startup on a harddisk, then someone comes with his/her own
   system disk (OD) and boot from the monitor with bod. Is he or she going
   to have ALL the access of files on my harddisk as if he/she mount my
   harddisk under his/her home directory on his/her OD?

if both are true, isn't it very dangerous to let anyone use my cube? (well,
I don't have a harddisk yet, but I am plan to. A single optical drive system
is not so usable...)

so is there anyway to give the permission for excecute mount and unmount only
to certain user?  I read it in the user ref manual that sysadm can set it so
users cannot eject disk.  Does that mean users can mount disk but not to 
unmount disk?

mmm... I am getting more and more questions as I read through all these manuals
Thanx a lot to whoever can answer these questions.
