And as stated in my other reply to the patch:
partition needs 64 bit disk device support in AmigaOS or AmigaOS
like
operating systems (NSD64, TD64 or SCSI direct)
I'd probably leave it at 'disk needs 64 bit disk device support
on
native OS', and only print that warning once.
This is fine with me.
OK, I'll go with that.
Do we really need the warning?
Once the parsing is fixed doing 64-bit math, it does not matter for
Linux anymore.
Well, irony of this is: In my case the RDB has been created on a machine
with a native OS. So Linux warns me about something I already did so on
the native OS without any warning. In this case AmigaOS 4.0.
Exactly.
So moving a disk partitioned under AmigaOS 4.0 to a system running an
older version of AmigaOS can fail miserably. Not a Linux issue.
Linux also doesn't warn about disks with GPT failing to work on old MSDOS.
I would not name the kernel option "eat_my_rdb", but use a less
dramatizing name.
Maybe just: "allow_64bit_rdb" or something like that.
I don't expect to get away with that :-)
I still fail to see what's the added value of the kernel option...
Either the partition is usable, or not.
Well, I could try to contact some of the current AmigaOS developers
about that and ask them whether they would like to give me a statement
about this that I am allowed to post here.
I would not know whether they answer and it may take a time. My offer
stands, but I would only do this, if you really like to have that
official feedback.
Let me clarify: what exactly would the kernel option allow? When to use it?
Again, I am pretty sure that what I did is safe on AmigaOS 4 at least,
but I bet also on AmigaOS <4 with NSD64 or TD64 (except for the
filesystem sizes, but AmigaOS < 4 does not have JXFS anyway, and did not
have SFS2 as well, maybe that is available now, I don´t know).
However Joanne is without doubt an authority on RDBs, but she has not
As a former AmigaOS user, I'm fully aware of that (Thanks Joanne! ;-)
