I see your point, but I think it will not be easy for me to make it.
There are several multi-boot systems for USB drives that are easy to
create, but the ones that I know of for DVDs need remastering to be
created. Maybe somebody in the Lubuntu community knows how to do it and
would be prepared to make such a DVD image.
Can *you* how are reading this now do it?
2. One Button Installer on CD/DVD
I agree with Brendan, that Plop is a good alternative.

2.1 I use a Plop CD to start some drivers that can boot a USB pendrive
in my oldest computer, a Compaq Presario 5640 with a 400 MHz Pentium II
CPU and 192 MB RAM. That way I can use the One Button Installer and
install an operating system from a tarball.
2.2 A second alternative would be to make the OBI work from a CD/DVD. A
couple of alternatives might work:
A read/write CD/DVD system is possible but not very standardized, and
I'm afraid it might work only in a few CD/DVD hardware equipments.
Making an OBI iso file by remastering an iso system:
It would be more likely that a remastered iso system would work in most
computers with a CD/DVD drive (to make an iso file live system with the
OBI scripts included). I have never remastered a system, and need help
to learn how to do it or ask someone else to do the remastering, but if
many people want it, I think we should do it.
3. mkusb without sudo
Your question about mkusb should be easier to solve. I just tried to use
it without using sudo directly in the command line (but running as root
via sudo -s).
The current version works like that for me. But I found that there are a
few calls with sudo, that should be removed from the script (two calls
of parted and one of fdisk), the others are only text strings in echo
grep 'sudo ' ~/bin/mkusb
for i in /dev/[^f]d?; do sudo parted -ls|grep -B1 "$i"|tr '\n' '\t';echo
tj="$(sudo parted -ls|grep -B1 "$j"|tr '\n' ' '|sed s/Model:\ //;echo
tj=$(sudo fdisk -lu "$j" 2>/dev/null|grep "$j":|sed s/\,\ .*//)
echo "sudo $0 file.iso"
echo "sudo $0 file.img.gz"
echo "sudo $0 file.img.xz"
echo "sudo $0 wipe-all"
echo "sudo $0 wipe-1"
echo "sudo $0 $1"
echo "sudo lshw -class disk #####" > "$hlptxt"
echo "sudo fdisk -lu 2>/dev/null|grep "/dev/[^f]d"|sort #####" >>
Can you try it after removing those sudos yourself, or do you want me to
upload a release candidate to test?
If that does not work, there might be something else, that is used by
the bash script in an Ubuntu based system, that is not available in the
other system (in partimage linux). In that case, do you get an error
message or warning?
