This happens "automatically" as soon as the maintainer becomes aware of the
update and finds the time to do it. I always tried to get the latest snap
shot running, which happened to be the case for gnumach but not with hurd.

The current versions in Debian are gnumach-19981025 and hurd_19980716.

Sure, but this is not as easy as it may sound. The current libc6 maintainer
is overworked, and someone has to change the Debian building scripts and
remove linux specific things like architecture. So it will be faster to use
"our" version of glibc for now. Other ports are building from 2.1 pre
versions, this has to be investigated, too.

Ok. I hope I can do the packages this week.

We'll see. I encountered little libc6 problems during cross compilation, but
a lot of make file problems (due to cross compilation). If we can change to
native configuration, we have won a lot.

To answer your question, you've done your part. Now it is time for us to
catch up with your work. I am currently updating my CVS repositories and go
from there.
