- I am on Mac OS X arm64
- I have 1 USB flash drive, not 2 (easy to write live USB installer to one and install to the other)
- I do not have a Windows or Linux PC near by (can't format NTFS without pain, can't format ext4 without pain, etc.)
- I want to prepare a USB flash drive that can be booted via a separate machine (non-Mac) via EFI (not legacy MBR).
- I do not have Ethernet, just WiFi (no netboot capability)
- I wanted the root filesystem to be compatible between Linux + Mac + Windows (NTFS/FAT32/ExFAT/EXT4 options; none meet this criteria)
- I wanted to write Debian live image to USB stick, add
toramboot parameter, turn around and installDebianto this USB stick. Did not work, doesn't come withdebian-installer-launcherby default, had to add manually after manualwpa-supplicantconfig, then got a random error after partioning.live-toramalso didn't work.
