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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
