Re: universal boot USB stick?

[fred roller]

I don't know the use you have in mind; however, when I did service I just
made a live USB, shrunk and created a data partition JIC I needed storage.
Set the bios priority to USB when needed, etc etc.  Granted, this was a
basic OS but usually had the tools I needed and did repo install as needed.

Using other distro for job specific ofc helped, such as SystemRescueCD, for
more aggressive rescue ops...

For sure is unnecessary. And you won't be able to Secure Boot because the
bootloader won't be signed.

livecd-tools still has livecd-iso-to-disk script that can create a USB
stick that's UEFI and BIOS bootable.

https://github.com/livecd-tools/livecd-tools/blob/master/tools/livecd-iso...

The optional persistent overlay will eventually blow up and will have to be
reset. Avoiding that means doing a real install to the USB stick.
