[gentoo-user] boot to console only?

[gentoo-user] boot to console only?

[Mark Knecht]

Hi,
   What (if any) is a way to boot a Gentoo VM as far as the console,
not starting X, to allow a root login? Possibly some sort of
interactive boot where I can tell it to continue or not?

   The current kernel on this VM is 2.6.36-gentoo-r5 if it matters.

Thanks,
Mark

Put softlevel=single on the end of the boot line.  I think 
init=/bin/bash will work but I don't think it requires a password either.

Put gentoo=nox on the end of the VM's boot line at the boot loader.

Thanks to you both Adam and Dale. I found the nox keyword searching in
Google but couldn't figure out how to use it correctly. It does
exactly what I was looking for.

The problem was I built a VM that started X but only had KDE in the VM
and no user accounts yet. KDE starts and runs in the VM but KDE
wouldn't allow a root login so there wasn't a way for me to get a user
account added without stopping at the login like this.

Cheers,
Mark

Add gentoo=nox to the kernel parameters.

If you want to start X later, run /etc/init.d/xdm restart.

I define a separate run-level for no-x*, which doesn't contain xdm and 
also omits various other things that are only needed when running an X 
session (lm_sensors, vboxdrv, alsasound, ...). Then I put a separate 
entry into grub.conf for it and select it at boot time.

It doesn't get used very often, but when I need it nothing else will do. 
Very handy for, e.g., major upgrades of KDE, when I'd rather not carry 
on running old-KDE and risk starting a program thoughtlessly that might 
be either old-KDE or new-KDE.

Single-user mode won't do for this because I want the range of VTs to be 
available to do work in.

*  like this:
# mkdir /etc/runlevels/no-x
# rc-update add <package> no-x

Uhm, CTRL+Alt+F1 will switch you to the first console so you can login 
as root.  If you're on VMWare, that shortcut becomes CTRL+Alt+Space, 
release them, then press F1.

With rc_interactive="YES" in /etc/rc.conf (with baselayout2, I'm not
sure how that was enabled with baselayout1) you can press the 'I' key
during boot to enable interactive mode. You are asked then for every
init script if it should start or not.

But if you only want to avoid X, the other solutions that were posted
are better. And switching to a text console probably is the easiest.

That's what I do on a physical Gentoo box and it works fine. (Either
Alt-Ctrl-F1 or Alt-F1)

This VM, running in Virtualbox-4.0.0 on Win 7 didn't work. A more or
less identical Gentoo VM running on a Gentoo server (yes, Gentoo
within Gentoo) didn't switch to the VM's console but switched to the
server's console. Assuming I was actually capturing keyboard strokes
by the VM that doesn't make sense to me but possible things like Alt &
Alt-Ctrl sequences are handled differently by Linux. Dunno..

Anyway, the gentoo=nox solution worked great for my needs.

Thanks,
Mark

Ctrl is needed when in X11.  When in a console, only Alt is needed.

It's always good to be able to switch to the consoles without needing a 
reboot.  Since you're on VirtualBox, maybe this helps:

That works great. Thanks!

Default setup is <Right-Ctrl>-F1 to get to the console as Right-Ctrl
is the VB default host key. I was always using Left-Ctrl yesterday.

Again, thanks!
