I'm saying that I was able to install AmigaOS 3.9 in Linux directories and the locale files looked like the right fancy European characters. I'm not sure which ISO standard the Linux file system uses for the characters but I know that Linux has more flags than AmigaOS users usually pay attention to but, now that you mention it, most of them are geared toward multiuser environments and not single-user workstation environments like Amiga...
You're probably right. I just ran into fewer problems using a directory than using a hardfile under Linux.
