Log messages during init (between kernel boot and login)

I was wondering if there was some way to log console output during the init process in Arch. I just installed Arch, and right now I know alsa isn't working on boot, but I can probably fix that. More generally though, it'd be nice if there was a log of what happened between the kernel boot and the console login (I know I can keep it from clearing, but that's not quite what I was looking for). If Arch doesn't have a built-in way to do that - maybe I could hack the init process myself somehow to do that? I checked all the /var/log messages, and everything I saw was basically a repeat of dmesg; no daemon messages.

Re: Log messages during init (between kernel boot and login)

Hi.
I have similar problem. At the end of the booting I see fragment of some error message, but it's immediately cleared by getty prompt. None of the files in /var/log nor dmesg output contains the fragment I remember.
It's something related to loading VirtualBox modules, in dmesg and /var/log/messages.log are these messages:

Jul 23 15:36:10 vociland vboxvfs: Unknown symbol vboxadd_cmc_open
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol RTLogBackdoorPrintf
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol vboxadd_cmc_ctl_guest_filter_mask
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol RTErrConvertToErrno
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol vboxadd_cmc_call
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol RTAssertDoBreakpoint
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol vboxadd_cmc_close
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol AssertMsg2
Jul 23 15:36:10 vociland vboxvfs: Unknown symbol AssertMsg1

I don't want from anybody to help with VirtualBox issue. The problem is that during the boot, the error message seems to be "human readable" and I would like to see it before asking for help. What is needed to retain these init messages at the first console like I seen it in Gentoo or Ubuntu?

Thanks for help.

Scroll lock key will pause booting too.
