For the record, you can already disable Joliet support with <Alt>-<J> in 
Rufus, which I tested, allows it to proceed with the 
livegui-amd64-20220605T170549Z.iso image. I haven't tested actual boot 
with the resulting media at this stage.

Note that I am seeing another issue with the Gentoo image with a report 
of "Bad directory information for isolinux" (from [1]), which I think 
might have to do with the same issue, as it goes away with Joliet 
disabled and this message is produced when the 
_iso9660_dir_to_statbuf(..., p_iso->u_joliet_level) call fails.

I am in the process of releasing Rufus 3.19 BETA (which must happen 
today for varied reasons), but I'll see if I can squeeze Thomas' patch 
for the 3.19 release, which should be about one week for now. I can't 
promise anything though, especially as I'd want to eliminate the 
isolinux issue for that release too...

Regards,

/Pete
