Dependencies

To generate iso image

  • mtools xorriso (which is libisoburn on ArchLinux)
  • gcc >= 6
  • sfdisk (util-linux)

Run it

make run

or

make fd.iso && qemu-system-x86_64 -cdrom fd.iso

you can also test it

make test

Debug

gdb could be launch with debug symbols using :

make debug

Serial log will be saved in the serialOut file.

Then you can check some matos specific commands or pretty printing with

help user-defined info pretty-printer (Should contains matos_pretty_printers)

Change Disk partitions

You can either modify the disk.sfdisk file

or

modify the disk image with your favorit tool (e.g. gparted) and re-generate disk.sfdisk

sfdisk -d > disk.sfdisk
