If you'd like to live without all /proc-using tools, much of /sbin,
the X server, inetd, anything that uses sendfile(), and anything
that uses RT-signals for IO events... go right ahead. You can give
up on VFS enhancements too, since anything using them wouldn't be
portable to AIX, Ultrix, or OpenServer.

Partial list of non-portable system calls for you to abstain from:

mkdir have fun, because this isn't portable
sigaction you know what to do...
setreuid
symlink you can use the v7 filesystem too
iopl obvious
clone
setfsuid didn't Ted come up with this one?
poll can't use select either
prctl comes from IRIX, not v7
pread SysV, isn't it? Must be bad!
sendfile just some benchmark hack

SCO has some UNIX source that might be more to your
liking than Linux is.
