✨ NAME ✨

okay so bestie, meet update-grml-rescueboot — it's the script that integrates a Grml ISO so you can boot it via GRUB 💖 no cap, that's literally its whole job description.

🌸 SYNOPSIS 🌸

update-grml-rescueboot [-f] [-t small|full]

that's it. that's the whole summoning ritual 🎀

🦋 DESCRIPTION 🦋

okay so picture this: grml-rescueboot is the thing that integrates Grml ISO booting into GRUB. it hands you a script for update-grub which goes looking for Grml ISO images in /boot/grml, and then — automatically, no asking — adds an entry for each image it finds. the whole point? you get to boot a Grml rescue system using one of those images instead of dealing with a CD, a USB stick, or network boot (PXE). so very 2009 of those alternatives, we don't do that here 💅

and then update-grml-rescueboot itself is the script that does the legwork. it checks for the latest stable version of Grml (via download.grml.org), makes sure there's enough free disk space in /boot/grml, and downloads the ISO to /boot/grml. it verifies the ISO signature, and upon success it executes update-grub then. after that? everything should be ready for booting a Grml ISO via GRUB. periodt ✨

so basically this script makes integrating a Grml ISO into GRUB via grml-rescueboot even easier. all that needs to be done is install grml-rescueboot and then invoke update-grml-rescueboot. that's it. and using the -t option, it's possible to use specific Grml ISOs. if this option is not specified, it defaults to the full flavour matching the hardware architecture (amd64 or arm64). iykyk 🧚

💅 OPTIONS 💅

  • -f — force execution, ignoring, e.g. existing ISO files and disk space checks for /boot/grml. it's giving "i know better than the safety checks" energy, use responsibly bestie 😭
  • -h — display usage information and exit script. the classic "help me" button 🫶
  • -t arg — choose Grml flavour, specified via arg. supported flavours are 'small' and 'full'. if unset, defaults to 'full'. pick your fighter ⭐
