Yes, no, sorry, I mis-spoke. I have partitioned the disk in Linux, now I
would like to format it in Linux also, but AFAIK there is no format tool in
Linux that can format Amiga partitions, correct?

I set up the first disk on my Amiga2000, and I think I could set up and make
AmigaOS bootable on it:
Disk /dev/sda: 64 heads, 31 sectors, 246167 cylinders, RDB: 0
Logical Cylinders from 2 to 246166, 1015808 bytes/Cylinder
(the second disk says here:
Logical Cylinders from 2 to 246166, 512 bytes/Cylinder
is this trouble?)

The two Amiga partitions are both smaller than 1GB, so there should be no
problem to handle the Amiga partitions? hdtoolbox has a problem with the big
disks, thats why I partitioned it in Linux. Maybe, when I first set it up, I
only created the two Amiga partitions, but I will leave this to Ingo to
figure out ;-)
My AmigaOS manual says under hdtoolboox, see the Amiga harddisk manual, but
my A2k came without harddisk, so I don't have this manual.

That is the plan, I just need it to boot, maybe hold the installer files to
test the installation, and a couple of kernel images. Alas, the partitions
do not even show up in the early boot menu, even though the 1 partition is
bootable, so there is no chance to format it. I must be missing something
obvious, hdtoolbox can see the partitions, but nothing else can. Yes, I did
reboot.

I tried that also, I had these filesystems on my A2k, but they were beta
versions and have long since expired. I think I found some patches on Aminet
to remove the beta status, but I did not quite get it to work. And as you
said, with the "small" partitions (my first amiga disk had 100MB...) it
should not be necessary. It has been a while that I used AmigaOS, and I
don't think I will go back...
