I think it is good to have a portable live or persistent live system on a USB pendrive.

Reasonable if you intend to use it to install, but it is better for a portable system, if there are no such limits. > >> What would be needed to make a 32-bit system 'licensed' to run in >> UEFI? >> > What makes you think you need anything licensed to boot with UEFI? Reading the discussions about UEFI, and how people are trying to make it dual boot with Windows 8 in UEFI. Maybe licensed is the wrong term, maybe the term is 'a key'. Try to boot a USB drive, any 32-bit Ubuntu family version! It will not work. All these USB pendrives work when I switch UEFI off. But this is not possible in some computers. Clonezilla i686-pae boots from CD, Lubuntu 12.04 i386 non-pae boots neither from CD nor USB. Lubuntu 12.04 64-bits boots from CD. Ubuntu 12.04.2 boots from USB, but I think it is 'licensed'. A brand new download of debian-live-7.0.0-amd64-lxde-desktop.iso does not boot from USB, but it boot fine when no UEFI. > >> I tried recently with a grub2 and iso system in a USB pendrive.

I can try again, but what I know is that for example Ubuntu 12.04.2 boots from USB repeatedly without any problems. A 32-bit system with the same 'license' or 'key' should work too, and would be a good candidate for a truly portable system. > >> I think an iso for 'all' intel/amd computers would be interesting >> also for Xubuntu. >> >> I'm willing to test it in low-end and high-end computers, but I >> don't know how to create it. >> >> Best regards Nio -- Mailing list: https://launchpad.net/~lubuntu-comms Post to : lubuntu-comms@lists.launchpad.net Unsubscribe : https://launchpad.net/~lubuntu-comms More help : https://help.launchpad.net/ListHelp
