kernel+apps+base+tools: Use Ext2 for the root partition file system
...
continuous-integration/drone/push Build is passing
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.
