= Project "tiniest"

This project is an experiment of building a tiny linux boot system
with a single, common syslinux boot configuration used for both legacy
bios and UEFI bios.

The script +mkit.sh+ prepares such a +bootimage.raw+ and the script
+vm.sh+ runs a Qemu VM for testing it. In addition, the script
+packit.sh+ runs xorriso to prepare an ISO with that boot image, to
boot either as cdrom for legacy bios or with EFI partition with for
UEFI bios.
