Currently it is stunningly small (if df / tells the truth).
But i will re-install to a 32 GB "disk" before i invest more time into
exploring and installing.
For now i built my own upstream packages and got the test cases running,
as far as applicable without contact to a CD drive.

Testing is still quite obscure to me. So first i will concentrate on
making a plan.
After re-install i will try to get the Hurd sources.
Then i'll try to identify the point where device_get_status() materializes
on the kernel side. From there i'll have to find a path to
scsi_ioctl_send_command() (which i yet only know from googling).

Not yet. I'm quite asynchronous.

That's what i tell myself since i began driving CD burners, five years ago.
(USB boxes brought a big relief for the pain of rebooting because of
a stuck drive. I hope that virtual machines will do the same for
kernel adventures.)
Well, i will see how far i get.
... Now i installed basic Hurd in 32 GB. All looks well so far.
Except i cannot find out why logging in from the hosting system by
ssh -p5555 localhost
demands a password.
With the previous installation it sufficed to copy .ssh/authorized_keys
to silence the password prompt.
There is no file
~/.ssh/known_hosts
in the new installation. But copying from the old one does not help.
Neither ~/.ssh/* nor /etc/ssh/* show differences which would give me a clue.
Somehow i do not have this system under control yet. {:|
Have a nice day :)
