init is now split into two parts: preinit, which lives in the initrd and prepares the root file system for init,
and the actual /usr/bin/init, which lives in the root partition and starts services and reaps zombies.
The kernel now looks for /bin/preinit instead of /bin/init as the executable for the init process.
All configuration files in initrd/etc have been moved to base/etc. (The plan is to have only moon and preinit in the initrd.)
Since the current Ext2 implementation is read-only (and it's on a CDROM so it would be read-only anyways),
/home/selene is a tmpfs (as well as /tmp), to allow for a writable home directory.
The system is slower now, but that's to expect since the Ext2 code doesn't use caching and the ATA code still uses PIO.
This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc.
No read/write support, so file descriptors are kind of useless for now.
getpwent, getpwnam, getpwuid... they may have been a pain to implement but once they work they're awesome :)
Right now passwords are stored in plaintext in the world-readable passwd file, which is not good.
But I don't have any sort of hashing implemented so it'll stay that way for now.
