Re: [gentoo-dev] New Install Instructions

[George Shapovalov]

Some programs might need to have access to /proc during bootstrap/emerge 
system after you chroot. 
mount -o bind /proc /mnt/gentoo/proc
does just that - "mirrors" /proc contents under /mnt/gentoo/proc (which will 
become new /proc after chrooting).
With kernel 2.2 (and correspondingly older mount) you cannot use -o bind 
option, but you can mount proc for the second time with:
mount -t proc none /mnt/gentoo/proc
that will take care of it, and this is what I did in such situation (and BTW 
this should work for 2.4 as well, just not that elegant, as in my case upon 
umounting proc mtab was not updated properly. Really minor issue, especially 
considering that the next step is a reboot :-) (and I was not using a full 
path when mounting, that might have been a problem).
