Hmm. AFAIK "weirdnix" is just alias for "not quite straight Unix
implementation", no ? And my point was that why we need Linux is we want
JUST unix ??? There are already exists "just unix". Even free one (*BSD).
Of course we should not stuff Linux with additions without thinking.

There are limited number of mountable filesystem AFAIK. If you have
500-1000 users you just can not mount ipcfs, procfs, devfs for each...
You CAN provide sane environment with hardlinks, though...
