The only thing that really depends on /sys is the autodetection in 
mkinitcpio - if you're going to boot this on another machine, you'll 
have to boot the fallback initramfs anyway, so it doesn't matter.

I remember some install scriptlets look at files in /proc, but not 
having /proc shouldn't make problems either.

The only thing you really need is /dev - or at least some nodes. If you 
don't want to bind-mount /dev, you need to create at least /mnt/dev/null 
(maybe also zero, not sure). On udev installation, 
/dev/{zero,null,console} are created there anyway, but that happens later.


Note that our installer also bind-mounts proc, sys and dev from the live 
system to the installation system - it's safe and can avoid problems.
