Quick-init - Boot your arch in 10 seconds

PKGBUILD - If you like it vote it

After the incompatibilities of finit-arc system I decided to resume the quick-init project.
The goal of the projects is to make a faster linux boot without any problems in full security smile without replace the original arch initscripts, but only replace of /etc/inittab. Then the initscrips is not removed from your system with this PKGBUILD.


WARNING!
If you have installed quick-init < 1.3-1 you must remove it and reinstall initscripts!


HOW IT WORKS
The reimplementation of init-scripts consists in the modification of the inittab runlevels and the start of system and Xorg without udev.
The first system level contains the creation of static devices necessary to boot system until fscheck. Then Xorg is started and in runlevel 3 it starts udev, swapon, all services etc...
Quick-init is almost fast than finit-arc. At the moment quick-init should be full compatible with your system, but it stay in experimental state.


OPTIMIZE FURTHER YOUR BOOT
If you want optimize your boot you can remove some lines from qinit.sysinit and qinit.multi. For example: lvm support, raid support, the load of modules...


FAST START X MODE (Xorg, Gdm etc..)
If you want start your gui fast you don't use a daemons like gdm becouse it starts in final part of the boot. You can use inittab or rc.local.
- INITTAB: read http://wiki.archlinux.org/index.php/Start_X_at_boot
- RC.LOCAL: Edit /etc/rc.local and insert command for start your login-manager, for example: /usr/sbin/gdm --nodaemon

At the moment fast start of X works 100% with:
- ATI chipsets with radeon driver
- Intel chipsets with i915 driver
- some nvidia chipsets

To know if fast start X mode works with your chipset you can try to start your X session without udev after qinit boot. To remove udev start edit /etc/qinit.multi. If X starts without udev, the fastest start will work, otherwise no smile

Suggestions:: you could use xorg-server-antidesktop: a light version of X server without Hotplug support. Then you can remove /etc/rc.d/hal start from qinit.multi and further reduce your boot time wink

Re: Quick-init - Boot your arch in 10 seconds

Too bad it doesn't speed my system that much, tried to take out the udev part, but indeed X didn't want to start.
What else did you do to optimize your boot?

Re: Quick-init - Boot your arch in 10 seconds

So do I just install this and reboot, or is there some other stuff I have to do?

I ask because last time I tried these scripts I couldn't boot, and I don't want to go through that again.

Re: Quick-init - Boot your arch in 10 seconds

This didn't speed up my boot at all, and worse, didn't save my old inittab file.  Luckily, I had an old inittab.pacnew file from January hanging around in /etc.

Re: Quick-init - Boot your arch in 10 seconds

I know that quick-init dont save the current inittab but save a default copy. This becouse if you have installed a previous version of quick-init it saves the inittab (really quick-init tab), then the user lost the default inittab from his system.

Is it for any type of system or just for the eeepc?

Re: Quick-init - Boot your arch in 10 seconds

Adriano, I really think you should save the user's inittab (and not just the default inittab) on quick-init install. The way it is now, anyone who installs quick-init *loses* all the changes that may have been done in inittab. The fix is really easy: just use 'cp /etc/inittab /etc/inittab.user.save' in the install script of the quick-init package [and adjust the messages accordingly].

Also, the thing with leaving sd* devices in /lib/udev/devices after the uninstallation of quick-init is:
1) no pacman package should leave any cruft in the system directories after uninstallation, because this leaves files in the system that are not tracked by pacman (this is just a packaging standard for me, not a problem per se)
2) the possible problems come when the user adds or removes harddrives from the computer - then kernel may decide on different naming of the devices. That introduces a problem that udev can't react on this, since the nodes that are left behind are static. This is of course expected when one still uses quick-init (maybe you could include a script that regenerates the nodes with your package), but after the removal of quick-init users still can get unwanted behavior (and this shouldn't happen).

In the arch packages' install script you can use two different functions: post_install and post_upgrade. The original user's inittab would be saved in post_install (then it's clear that quick-init is not on the system), and nothing would be saved in post_upgrade - that way you really keep the user's inittab saved.

Re: Quick-init - Boot your arch in 10 seconds

wouldn't boot on my system... hung on checking filesystems... complaining that I should run a manual check... doing that did nothing...

if I uninstall quick-init with pacman is there anything else I need to remove to remove it fully from my system?

Re: Quick-init - Boot your arch in 10 seconds

seems to be a great addition for me. Installed on Intel(R) Core(TM)2 Duo CPU  E8400  @ 3.00GHz with Nvidia GeForce 9500 GT

My first time install brings  bootchart time (with bootloader set-up)  down from 22 secs to 10 secs.

Further attempted "tweaking" does not seem to improve on this though- if I really need , or am able,  to .......................

I am not quite clear on :
"- INITTAB: Uncomment your preferred level in the /etc/inittab. The principal levels for login managers was written by me as comments".

I have tried uncommenting lines .Is it possible for further explanation ?

adding a line to RC.LOCAL does not seem to improve boot time. I appreciate my bootchart times are only showing timing up to login...............


"It seems to work fine, but while shutting down I've got message that stopping hal failed..."

I get the same message on shut -down as above. Everything seems to be working fine ,so is it a problem ?

good work adriano

regards

Nothing was wrong, It's just that he suggested to use X without HAL so it would boot faster, but I'm just not into that.

Re: Quick-init - Boot your arch in 10 seconds

One more observation: the xorg runlevels shouldn't be :2345: but :5: only. i.e.:
xorg:5:respawn:/usr/sbin/gdm -nodaemon
instead of
xorg:2345:respawn:/usr/sbin/gdm -nodaemon

Otherwise, the standard kernel command line runlevel selection won't work; one would append a '3' in grub and still end up in X.

Re: Quick-init - Boot your arch in 10 seconds

no, Xorg must start in runlevel 3 to start in background X

Quick-init UPDATED to version 1.9-1
