What is is : a way to impliment "MVS", a security scheme in which the
entire system is not controled by a single superuser, root account.
Administrative resposibilities are spread between multiple accounts.
Good reading : http://www.linuxsecurity.com/feature_stories/feature_story-7.html
Why you need it : Need is a strong word. It is a better, safer, more
secure system (provided it works as advertised), but it is not the
only way to improve system security.
How to stop the failure : You prabably have two options here. The
easiest is to simply prevent it from starting. In /etc/rc.d/init.d
(or /etc/init.d , I don't recall which way RH does it) is a script
file called medusa (or something similar) This is the file that is
being called and failing. It is being called via a symbolic link from
one of the /etc/rc.d/rc?.d directories (where ? is some number,
probably 3 or 5) called S??medusa (S is for startup and ?? is a number
00-99) Delete these links and you won't get the failure message. The
harder and more complete way would be to fully install medusa as it
was meant. You installed a medusa rpm as part of Nautilus, but to
truly impliment MVS, you need to patch and rebuild your
kernel. (Something all new linux users should do eventually) For that
I suggest you seek out the HOWTO on building the kernel from source
and the medusa website : http://medusa.fornax.sk/
