[gentoo-user] How can I re-read the "error" messages during boot?

[Pandu Poluan]

I rebooted a Gentoo system, and as I watched the boot-up messages,
some "error"s appeared when it's starting the services. However, the
screen scrolled too damn fast for me to read them.

Where can I find the logs on the services? Or is there a way to slow
down booting?

You can press 'I' during boot to go into interactive mode, and then
OpenRC will ask you before starting any service. You can also call
rc-status to see the status of each service.

If you set rc_logger="YES" in /etc/rc.conf, you can find the boot log
in /var/log/rc.log.

Try pressing Ctrl-S to stop the output. Ctrl-Q to continue.

Thanks, Alex & David.

Yeah, *just* noticed there's an 'rc_logger' setting in rc.conf, before
reading your emails :-P

But thanks for the help, anyways! Much appreciated :-)

Enable logging or you may find it with dmesg
grep rc_logger /etc/rc.conf
then you can grep errors
grep WARNING /var/log/rc.log

'Shift-PageUp' works for me: IIRC you have to set the line limit
& that mb somewhere in the Kernel configuration.

If you use fbcon there is a kernel parameter to increase the buffer
size. I don't remember the exact command but it's in the docs.

I think the default buffer is 32k and can be increased up to 128k or
so. The size of your font may impact how many "pages" of scrollback
you get.
