Subject: [PATCH] Single user linux

hi,

a friend of my asked me on how to make linux easier to use
for personal/casual win user.

i found out that one of the big problem with linux and most
other operating system is the multi-user thing.

i think, no personal computer user should know about what's
an operating system idea of a user. they just want to use
the computer, that's it.

by a personal computer i mean home pc, notebook, tablet,
pda, and communicator. only one user will use those devices,
or maybe his/her friend/family. do you think that user want
to know about user account?

from that, i also found out that it is very awkward to type
username and password every time i use my computer.
so here's a patch. i also have removed the user_struct from
my kernel, but i don't think you'd like #ifdef's.
may be it'll be good for midori too.


	imel
