Kernel and Initrd filenames not correct in Foreman Full Host disk image

Support
1

We have created a new bootdisk for Ubuntu but the boot variables are not
correct in it.
We mounted the iso image and found that the kernel and initrd filenames are
not matching the filenames in syslinux.cfg

I think foreman_bootdisk is miscalculating the maximum length of the
filenames that the ISO9660 format supports, as it's not taking into
account the "linux"/"initrd_gz" extensions.

Can you try to edit
/opt/theforeman/tfm/root/usr/share/gems/gems/foreman_bootdisk-8.0.1/app/services/foreman_bootdisk/iso_generator.rb
on your server? Towards the bottom is iso9660_filename and two mentions
of "0…30" - change these to something much shorter, e.g. 0…20, then
restart Foreman (touch ~foreman/tmp/restart.txt, or restart httpd). If
that works then I'll write a more correct fix.

still NOT FIXED:

This only appears to be one character out, having the last "z"
truncated. Just shorten the filename again, e.g. 15 rather than 20.
