Re: findiso
Is it necessary to put vmlinuz and initrd with the iso file and name them on the boot cmdline? Or does live-boot just find the iso and boot from that?
label Sid snap
menu Sid snap findiso
kernel /sid/vmlinuz
append initrd=/sid/initrd.img boot=live union=aufs findiso=/sid/sidsnap.iso
# Select iso file, mount it, select kernel and initrd from mounted iso.
# Copy kernel, initrd and iso file to same target directory.

* Added option for user-set loopback file size.
* Moved function check_size to functions file, so mkloopback could use it.
* Renamed mkloopback.sh to mkloopback.
* Update (replace_live) now works with multiboot.
