Top Forums UNIX for Beginners Questions & Answers Why bind to LiveCD /proc before building initramfs ? Post 303001806 by Corona688 on Friday 11th of August 2017 01:34:10 PM

It is certainly not archiving the contents of /proc. It's important that the dir exists and has the right permissions.

It might archive a tiny, minimal portion of /dev - just basic device files like /dev/console necessary for a system to boot.

Mostly, I think, what's happening is tricking it into building it from the given kernel instead of the running one.
