Re: linux kernel without users

I am interested in whether anyone has removed the user id code from
the linux kernel. Maybe for an embedded, single user, capability
based, or other unusual project. I mean to remove all references to
uid,gid,euid,suid,fsuid in task_struct and everywhere else in the
kernel.

There are lots of embedded Linux systems. I don't know of any that are
single user. It's the drivers and files that take up room.

Some of the early Unix systems had very little memory compared to
nowadays. I ran a VAX 780 with 50 users. It has a max of 1MB of RAM.
