Lately I have locked myself out my gentoo linux box and not been able to log on to root.
This situation happens to most of Careless! Linux users, but thanks to the GRUB flags, one might
able to overcome this situation with ease.
my /boot/grub/grub.conf looks like this
on your machine, you can do
1. $more /boot/grub/grub.conf to view yours
default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux
root (hd0,0)
kernel /kernel-genkernel-x86-2.6.17-gentoo-r7 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda3 doscsi
initrd /initramfs-genkernel-x86-2.6.17-gentoo-r7
2. Now reboot the machine, and at the grub menu press ‘e’ then ‘e’
now what do you wanna do is boot the machine to single mode.
3. Go down to the line kernel /kernel… and add ‘1′ to its end. you’ll wind up with:
kernel /kernel-genkernel-x86-2.6.17-gentoo-r7 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda3 doscsi 1
4. Now press ENTER and ‘b’ et voila.
