Created attachment 150407 [details] diffs to various mkisoimage.sh scripts When a release is generated, one of the steps near the end is typically creation of bootable iso filesystems. (Obviously, depending on exactly what is being built.) The different mkisoimage.sh scripts alway place a fstab file in the generated iso filesystem - ideally this would only happen when generating a bootable iso filesystem. I've had a local patch for quite a while to change the behavior to only generate the fstab files when the filesystem is bootable. I use the same mkisoimage.sh script to generate an upgrade.iso filesystem too, and that isn't bootable, and should not have a fstab placed on it. Anyhow, a patch to implement this is attached.
It seems sensible to me to avoid putting /etc/fstab on non-bootable images so I agree the idea is sound.
