Oops, you're right, telinit 1 doesn't work as expected in Gentoo (are there 
any bugreports about it?). However, I can reboot into RL 1 just fine and 
umount /usr w/o problems. I can also use ls just fine with /usr unmounted, 
all fs maintenance tools should also work.

However, after trying it out, it seems that even telinit 3 (when booted into 
RL 1) doesn't work properly, so using a LiveCD indeed looks to be the 
better option for the moment.

Bye...
