[Bug 914926] Re: no loop module - alternate-amd64.iso current precise

[AndreiF]

This is actual for i386 and amd64 distribution using hd-media initrd.
Bag is in hd-media initrd. First of all, if there are more than 10
images, after iso-scan 10 of them assigned to /dev/loop0-9.

The other mistake is "modprobe loop" in /var/lib/dpkg/info/iso-
scan.postinst. This not need for using kernel, this feature is compiled
in kernel. If I open with Alt+F2 the first console, the partition I need
already mounted in /hd-media. So the command "mount /hd-media/dir
/ubuntu-server.iso /cdrom -t iso9660 -o loop" work good. But script
/var/lib/dpkg/info/iso-scan.postinst exit with code 1, and don't ask me,
what iso it would select and mount.

  Many of us use grub2 to loopmount ISO files to install either from
  another drive or flash drive. With flash drives now lower in cost for
  larger capacities, I usually install several versions in one flash
  drive and use grub2 to loop mount the ISO files.
