The information at: https://packages.debian.org/buster/petitboot https://manpages.debian.org/buster/petitboot/petitboot.8.en.html was just enough to tantalize. Some references imply it remedies some Grub features I dislike. https://wiki.debian.org/accessibility#Complete_accessibility states:
That reference gives instructions for installing on a standard Debian system. This weekend I will install it on a laptop dedicated to experimentation to verify it gives the desired user experience.Petitboot provides the list of kernels to boot, and permits to append parameters, and then uses kexec to boot the desired kernelwith the desired options.
I've found references {e.g. https://www.raptorengineering.com/content/kb/1.html} which discuss creating a bios rom replacement. As a minimalist, that grabs my attention. How small can a partition be whose sole purpose is running petitboot.
I'm looking for links discussing petitboot itself and surveys of how people have used it on standard desktops/laptops.
TIA
