I'm trying to rebuild the kernel, and have been somewhat succesful. The only step missing is building the "initrd-image". This I can however not do, as mkinitrd is failing (ERROR: All of your loopback devices are in use!). A bit of googling turned up these postings
that I believe is an accurate description of my troubles (lsmod | grep loop returns nothing, and I can not find loop.[o|ko] in /lib/modules/`uname -r`).
The abovementioned postings recommend booting from a live-cd with a stock kernel, mounting whatever neccesary and then doing mkinitrd. I however do not have a live-cd (or arch install cd) available, so I was wondering whether it would be possible to just compile loop.o for the running kernel and the modprob'ing it? Any suggestions would be welcomed.
PS. I'm also a bit curious as to why loopback support is not compiled as a module in the stock kernel (I believe it was recently updated with pacman). Has something gone wrong in this update, or is this an error of some sort?
