Eeepc "fastinit" reimplementations Finit is a reimplementation of the Eeepc "fastinit" program based on its
---------------------------------- system calls with gaps filled with frog DNA.
finit.c is a reimplementation of the Asus Eeepc fastinit program based Finit's purpose is to build upon the general workings of fastinit and
on its library calls. It tries to be an accurate re-creation and keeps improve/optimize it for Xandros or alternative distributions running on
the original bugs and unoptimized calls. the Eeepc. Finit comes in three flavors: finit is a replica of the Asus
fastinit, finit-mod is an improved drop-in replacement for fastinit,
and finit-alt is a generic replacement for other systems. Finit-mod
and finit-alt were much improved with patches from Metalshark.
finit-mod.c is a fixed/improved version of finit.c intended to be a drop-in See more information at http://helllabs.org/finit/
replacement for the original Eeepc OS.
finit-alt.c is a fixed/improved version of finit.c for alternative Linux
distributions running on the Eeepc (previously ffinit.c). It's currently
able to boot Mandriva Linux 2008.0/2008.1.
See Makefile for configurable parameters to better suit your system.
* Eeepc boot process Usage scenarios
---------------
The essential steps in the boot process carried out in initramfs are: 1. Replace the original Eeepc 702 fastinit (finit-mod)
ROOT=`sed 's!.*root=\([^ ]*\).*!\1!' < /proc/cmdline` 2. Allow fast booting in alternative Linux distributions running on the
mount -t proc proc /proc Eeepc and other netbooks (finit-alt)
mount -t ext2 -o ro $ROOT /mnt-system
mount -t ext3 -o rw /dev/sda2 /mnt-user
mount -t unionfs -o dirs=/mnt-user=rw:/mnt-system=ro unionfs /mnt
mount --move /mnt-system /mnt/mnt
umount -l /mnt-user
umount /proc
exec switch_root /mnt /sbin/fastinit "$@" </mnt/dev/console >/mnt/dev/console
If mounting the root filesystem fails, execute a maintenance shell. If
mounting the user filesystem fails, fsck and reboot.
* Utilities available in the Eeepc initramfs busybox: Finit-alt is distribution-specific. Currently it generates a finit-mdv
executable for Mandriva 2008/2008.1 systems. Smurfy ported it to
[ cat cp cut dd eeeXubuntu, and parts of his port have been merged to finit-alt.

sh sleep switch_root test true
umount vi
* Devices in the Eeepc initramfs /dev: Finit-alt features

console fb null ram0 sda1 sda2 sda3 sr0 tty0 Finit-alt reads configuration information from /etc/finit.conf. See
the source code for available options.
Reboot and poweroff Rebooting and halting
------------------- ---------------------
Stock reboot and poweroff utilities of a modern Linux distribution may not Finit handles SIGUSR1 and SIGUSR2 for reboot and halt, and listens to
work correctly with finit. You can replace them with simple scripts that /dev/initctl so standard Linux reboot and halt commands should also
send SIGUSR1 to finit for reboot, SIGUSR2 for poweroff. work.
Using finit with KDE
--------------------
If you use finit to start KDE with auto-login enabled, hal-based device
automounting may not work correctly. That happens because the session
is started before the system message bus, so add a "dcop kded mediamanager
reloadBackends" call in the user AutoStart to restart the client.
