Where is startup log?

[Leonti Bielski]

Hello!
I'm using SHR. I've installed some applications, did opkg upgrade and
now illume doesn't start.
It loads illume (I can see very nice progress bar), but then it return
to console which says something like:
om-gta02 login: 31 om-gta02 tty1ered by Angstrom om-gta02 tty1 SPANK SPANK!***

Anyways, where can I get startup log files to investigate the origin
of the problem?

Thanks. Leonti
