* efi
* bios
* auto setup bios device
* --prefix '(memdisk)'
* live
* check squashfs option
* python
- [x] comply with secure boot
- [x] choose to check squashfs or not
- [ ] bash
- [ ] mimic grubx64.efi.signed ←
- [ ] efi
- [ ] include fonts/unicode
- [ ] bios
- [ ] find & setup bios device
- [ ] rewrite in python
![Graph](todo.svg)
### Later
* arm
* keyboard layouts
* custom fonts
* live-media
* -mount-opts
- [ ] target arm
- [ ] make keyboard layouts
- [ ] make custom fonts
- [ ] target specific live-media
- [ ] -mount-opts?
