Do not duplicate syslinux on the ISO root filesystem
The solution to #7345 (closed) duplicates syslinux, both inside the squashfs and
on the image’s root fs. We could avoid that and use the in-squashfs
syslinux binary without root privileges by employing stuff like
fuseiso (in Debian), "squashfuse":https://github.com/vasi/squashfuse
(not in Debian, but see [1] below), and fakechroot (in Debian)
instead of a real chroot for running the syslinux binary. Or similar
tools.
Beyond eliminating the duplication of syslinux, we’d get the “mechanism to run post-upgrade scripts” mentioned in #7345-note_4, which may come in handy in the future.
[1] As an alternative to squashfuse it should be easy to make a
sudo-safe wrapper around mount -o loop -t squashfs ..., that checks
that the destination folder is writeable by the $SUDO_USER.
