Personally I call it "my job" and am doing my level best to replace myself with a very small shell script. Currently down to ~3000 lines. Matthew

Thanks. For completeness what I did for now: # vnconfig vnd0 install66.iso # mount -t cd9660 /dev/vnd0c cd/ # cp -r cd cd2 # cp bsd-mod.rd cd2/6.6/amd64/bsd.rd # cp site66.tgz cd2/6.6/amd64/ # mkhybrid -a -R -T -L -l -d -D -N -o install66a.iso -vv -A "Unofficial OpenBSD 6.6 amd64 autoinstall CD" -P "Copyright (c) 2019 Theo de Raadt, The OpenBSD project" -p "Thomas Bohl " -V "Unofficial OpenBSD/amd64 6.6 CD" -b 6.6/amd64/cdbr -c 6.6/amd64/boot.catalog cd2

Thank you for your quick response. It works now. Even better that the
tools in base are enough.
I'd be very interested to hear more about what your working on but
Nothing special. Only private stuff. I want to move from to-do lists to
scripts. I believe the buzzword is "infrastructure as code" :-)
meanwhile I think the command you're looking for is some variant
on this:
mkiso() {
Thanks. For completeness what I did for now:

I have put an insane amount of work into exactly this, also with
an eye to portably directing the process to other operating systems
and hosting environments.
I'd be very interested to hear more about what your working on but
meanwhile I think the command you're looking for is some variant
on this:
mkiso() {
# Create new iso
# From src/distrib/amd64/cdfs/Makefile
if on_openbsd; then
OSREV=$os_version # For easier copy pasta
mkhybrid -a -R -T -L -l -d -D -N -o "$iso_fn" -v -v\
-A "OpenBSD ${OSREV} amd64 autoinstall CD" \
-P "Copyright (c) `date +%Y` Theo de Raadt, The OpenBSD project" \
-p "Theo de Raadt " \
-V "OpenBSD/amd64 ${OSREV} boot-only CD" \
-b ${OSREV}/amd64/cdbr -c ${OSREV}/amd64/boot.catalog\
"$s_where"/cd
# -a all-files
# -R Rock Ridge
# -T TRANS.TBL
# -L Allow .-file
# -l allow 32char
# -d Omit trailing period
# -D not use deep directory relocation, ... Use with caution.
# -N Omit os_version numbers ... Use with caution.
# -o "$iso_fn"
# -v -v verbose
# -b boot_image
# -c boot_catalog
else
die_unsupported build/target combination
fi
}
mkhybrid and xorriso are basically the same tool in ways I can't
quite remember right not but could probably be persuaded to. An
invocation of one can be systematically converted into an invocation
of the other.
Enjoy.

Modifying installXX.iso via script
Hello list, I created an autoinstall bsd.rd (containing auto_install.conf and disklabel.conf) and a siteXX.tgz. For example with the tool isomaster I can manually edit the install66.iso and add bsd.rd and site66.tgz to the directory 6.6/amd64. This modified ISO can be booted from real and virtual hardware. The unattended installation works and is really cool! Now I want to go the extra step and automate the modification of the installXX.iso. I tried the tool xorriso: $ ls -l 6.6/amd64/ total 28544 -rwxr-xr-x 1 null null 10299545 Nov 17 18:00 bsd.rd -rw-r--r-- 1 null null 4680444 Nov 17 05:03 site66.tgz $ xorriso -indev install66.iso -outdev install66a.iso -boot_image "any" "keep" -add 6.6/amd64/ [1] This leads to this message when trying to boot: CD-ROM: E0 Can't find /cdboot I then moved cdboot from 6.6/amd64 to the root of the CD: $ xorriso -indev install66.iso -outdev install66a.iso -boot_image "any" "keep" -move 6.6/amd64/cdboot cdboot -add 6.6/amd64/ This leads to this message when trying to boot: CD-ROM: E0 Loading /CDBOOT probing: pc0 mem[639KB 2046M a20=on] disk: hd0+ cd0 >> OpenBSD/amd64 CDBOOT 3.44 boot> cannot open cd0a:/etc/random.seed: No such file or directory booting cd0a:/6.6/amd64/bsd.rd: open cd0a:/6.6/amd64/bsd.rd: No such file or dir ectory failed(2). will try /6.6/amd64/bsd.rd boot> When I move bsd.rd to the root of the CD too, I can at least start the installation by typing boot> bsd.rd But it would be nice if that wouldn't be necessary. When looking at the ISO files with isomatser, the only difference I can find is that on the modified ISO the publisher information is in all caps. I'm obviously doing something wrong. Any ideas or alternatives?
