> 1. Will my 30 gb IDE drive (or larger) will be fully supported ? In Linux I partitioned it successfully, but in AmigaOS I've got weird sizes of my HDD. I 'm confused, because install guide talks about partitioning in AmigaOS, so I can't access whole 30 gb in Amiga OS =(.

 I think HDFoolbox has difficulties displaying partitions on disks > 4GB, but
 it will nevertheless work correctly (worked for my 9GB disk). Alternatively,
 you can try Joanne Dow's RDPrep (rdp391.lha on Aminet).

> 3. Is there any performance boost on NetBSD in comparison to m68k Linux ? I have a 68030 board with 32 mb fast ram. Will it be enough to run complicated python scripts or something like BitTorrent on NetBSD ?

 No idea, the last time I ran Linux on the box was around RH5.0, and the disk
 became corrupted at some point. But as I have disk space galore at the moment,
 I might give Debian another shot.
