It does have a loopback.cfg, which is why grub can boot it from the
grml-rescueboot devised menu entry. The live image is mastered to use
Ubuntu's casper and the distribution itself is Ubuntu based. First
impressions are that it looks smart.
I boot from a USB stick, which doesn't give the fastest booting in the
west. From a CD it might be noticeably slower. Once the OS is going I
cannot say I'm disappointed with its snappiness.

How about a 'df -h'?
Filesystem Size Used Avail Use% Mounted on
/cow 1006M 191M 816M 19% /

/dev/sdc18 and /dev/loop0 are the ISO image. Note the 100%. /cow is a
copy-on-write filesystem; it will be in memory. I've some progams open
and did some downloading. Whatever happened to you would be a result of
running out of room on /cow and not the fault of too small an ISO image.
Take look at
https://help.ubuntu.com/community/LiveCD/Persistence
and see what you think.
If you are think of trying other distribution's ISOs you are going to
have to abandon grml-rescueboot and do it directly with your own grub
entries. Its not too hard but every distribution is different.
Actually, many ISOs are hybrid ones and dd to a USB stick is by far
the easiest route.
