What I ran into was *not* a limitation in the RDB format, but a bug in
the Linux implementation on it. After Joanne DowÂs change the 2 TB disk
was detected and handled properly by Linux. Also AmigaOS 4.x handles
those disks just well and I think also AmigaOS 3.1/3.5/3.9 supported
them, but I am not sure on the details on that, it has been a long time
since I last booted one of my Amiga systems.
Many classic Amiga users may not deal with such large disks, but AmigaOS
4 users probably still, and some of them may run Linux on their PowerPC
motherboards as well.
So I think the issue is worth fixing and am looking into submitting the
fix, which looks pretty straight-forward to me upstream unless someone
bets me to it.
