I'm just saying that you're not the only one getting the problem.

Finit-arc-git sensitive update
Try it now.

Changes:
- new static devices added
- LVM support (thanks to Jan Spakula)
- steps order edited (udev and hal could work now)
- code clear

udev works, and so does my keyboard

However, the clock still resets itself, causing a long list of "WRITE TIME IS IN THE FUTURE [FIXED]" errors at boot.

EDIT: I see that's on your list of known bugs. OK.

Everything bout the known time bug seems to wor fine - X and GDM loads blazing fast!

Thanks, this looks great, I will try it out.

You say UUIDs don't work. What about other /dev/disk/foo/bar devices? Like by-id names, or labels? Using "normal" /dev/sd* names can be annoying when I add a hard drive and Linux randomly decides it's /dev/sda now. Especially since I use a LUKS-encrypted swap from /etc/crypttab -- can I use /dev/disk/by-id/ there? Is this a planned feature, and if so, will it slow the init down? Or is it intrinsic to the method used to speed boot time?

Thanks again!

Hi all,

It gives kernel panic at boot (git version) (

adriano · 2009-05-10 16:49:53

only two people have a kernel panic I'm trying to know why...dgr48 can you contact me via jabber?

Finit-arc-git reupdated

Although I'm not adriano, I took a look at the code and the way it works is
that udev is not used at all to create the device nodes; the device nodes are
created manually from the finit-arc program, and to figure out which to
create, finit-arc parses /etc/fstab and looks for lines that begin '/dev/sd'
- and these nodes are created. That's one of the things that make so
blazingly fast - it doesn't wait for udev which looks at all the devices, and
waits for them to initialize.

One solution to this problem would be of course to run udev first... but that means a slowdown by 1.3-3 seconds (on my laptops), so *if* adriano would decide to go this way, I would vote for this to be an optional feature.
On the other hand, this was originally meant for netbooks, which rarely have more than one hard drive attached.

adriano · 2009-05-10 17:30:12

Hi bender. I tried your solution but it is not the solution...I tried it in a few days ago but if I start udevadm first, it doesn't create all devices, it stopped I don't know why. Then not all devices was created, for examples usb_xxx device or others...it works fine only if start it after..

EDIT:

Finit-arc-GIT newly UPDATE
- I tried to fix clock, it works for me
- Swap partition mount added
- Autostart HAL, DBUS for Xorg hotplug support

I'm getting those annoying segfaults at boot with the -git versions (20090509 and 20090510) on my core2duo laptop. Interestingly, the -git versions work ok on my desktop P3.

I had to revert to 0.2-3 for my laptop.

adriano · 2009-05-10 21:15:35

I'm working on this error. Try 20090511 now

Clock WORKS. Great job!

Swap doesn't work, though.

It was segfaulting on me as well at some point; what I did is running 'strace finit-arc' on a running system. That can tell you at which point it segfaults. Of course it might not be correct, since you're not supposed to run finit-arc on a normally running system, but it did help me to discover the problem (which turned out to be my own patch

Duologic · 2009-05-11 08:38:48

Times measured with Bootchart
Lightweigth almost stock Arch64 on Core2duo
No finit-arc: 18s (untill agetty, too lazy to configure boot into X)
finit-arc: 10s (untill X + Awesome)

after backgrounding deamons in rc.conf and minimizing mkinitcpio till bare minimum:
finit-arc: just below 10s (untill X + Awesome)
finit-arc-git 20090511: 12s (untill X + Awesome)

I've wrote http://wiki.archlinux.org/index.php/Twe … _boot_time which becomes pretty useless after finit-arc. If finit-arc becomes more stable, I'll try to make a wikipage about it too, if no one already did by than.

This one works. Good job!

adriano · 2009-05-11 13:29:25

Finit-arc-git updated
try latest git now it may be perfect...

Does this mean I can remove hal from my rc.conf ?

adriano · 2009-05-11 13:57:29

yesterday yes, now no

Duologic · 2009-05-11 14:56:01

as I said before, finit-arc-git slows down the boot process by 2s here, any ideas?

TigTex · 2009-05-11 16:37:22

Latest git doesn't load something ( keybord and mouse doesn't work) 20090511 (first one) worked just fine

frigaut · 2009-05-11 16:57:04

Great job. I had trouble initially with finit-arc-git (20090511), in which mouse and keyboard would not work, but it works not with 20090511-1 (just the opposite of the previous post...).
- Networks's OK.
- boot into console in 9 sec (was 16), X in 18sec (total) (was 30+). Impressive.
- swap doesn't mount. swapon -a solves it.
- Another small issue: vpnc does not work: error: "vpnc: can't initialise tunnel interface: Inappropriate ioctl for device"

same problem here, swapon -a helps.

oh, latest git-version here.

gartrog · 2009-05-12 10:16:17

There is a problem of access rights with latest git:
KDE can't start for it can't write to /tmp/.ICE-unix. Indeed I have drwx-----T instead of drwxrwxrwt. Everything is fine for /tmp/.X11-unix though.

Same here, 50090512 works, though.

adriano · 2009-05-12 12:32:05

Hi, probably I will leave finit-arc becouse I'm working at a new init project. Finit-arc is very fast but very incompatible too...the project is to modify the default init system and the goal is the full compatibility with Archlinux. I will open a new post for this.

Latest bootchart with the new init system:

It is not optmized and it contains ALL parts of rc.sysinit

Arch Linux
