Re: Gnumach/Hurd on 8 MB Boxes?
Hello Roland,
thank you for the clarifying words on UFS and the Hurd. That will really
help here! ;-)

Swap is not a problem. I'm already using a swap partition with Mach4 and
it's doing very well.

Great, I'll just test the ufs server instead.

So it's not necessary to newfs the filesystems or tunefs them etc? Where will
the translator bits be put on? Will the UFS filesystem be still usable for
Mach4/Lites after having booted the Hurd and settrans something?

yeah, but what about the os-bit?... Its not a very recent version of the
ext2fs tools there. I had tried making a ext2fs filesystem out of Lites
which worked well, but then, booting the Hurd resulted in a lot of problems,
which resembled very well the ones I experienced, once I've forgot to set
that os-bit (-o hurd...). Hmmm....

FreeBSD does know ext2fs via a kernel module, but alas, there is no mke2fs
for it yet. I didn't try to compiled the mke2fs sources though...
Thank you very much.
