Bug#831368: live-wrapper: output live.iso not isohybrid, cannot be booted from thumb drive
Thomas,
if I manually install syslinux-utils and run "isohybrid -u live.iso",
live.iso is updated in place and boot loading appears to work correctly
as a CDROM, BIOS, or UEFI. My expectation was that "lwr" would perform
this step, as live-build "lb" does.
Note that I then encounter a kernel panic caused by missing live scripts:
