I would agree on using syscalls to avoid long hacks and system-specific behaviour, but wiping / and mounting something over it is trivial. Besides, I often made the experience that syscalls can turn out to be very complex and intransparent. It may be a one-liner in C, but who knows what happens behind closed doors? > We already have pivot_root in ubase.

Well, sh doesn't work when you don't have a shell on your initrd (like I do), but you already explained that to him afaik. However, I think Markus just sketched the functionality in sh and implied it to be implemented in C regardless. Cheers FRIGN -- FRIGN <d...@frign.de>
