-This message to help sate curiosity, as well as to ask for volunteers.
-Until we are ready for alpha test, this is the last such message that
-will be posted here. If you want to receive further such messages,
-send mail to hurd-ann-request@gnu.ai.mit.edu and ask to be put on that
-(moderated) announcements list.

-
-What is already done with the Hurd:
-
-The filesystem is complete; it runs (read-only), and most of its calls
-have been tested and work. The filesystem is able to download
-programs, by a kludge similar to the kludge used to enable the kernel
-to download the first task. In the actual bootstap sequence, it will
-download the execserver.
-
-The proc and auth servers are completed; the exec server is nearly
-complete (for a.out, not for bfd).
-
-C library support for Mach and Hurd rpc stubs, and some of the mach
-and hurd specific code, is done. Much untested and probably wrong
-code has been written to implement Unix "system calls". A large piece
-of this (the descriptor management code) is believed by Roland to have
-some architectural flaw, but he isn't sure.
-
-Some small filesystem servers (shadow directories, for example) have
-been written, but have not been compiled, let alone tested.
-
-
-There are currently three things happening wrt the Hurd:
-
-I am spending nearly all my time getting things to boot and run. My
-work is currently directed toward that goal; in the immediate present
-I am working with Roland on getting the library in its near-final
-state (which will last a long time) to make compiling easier. It is
-because this is nearly done that I can send this message.
-
-Roland is working on the library. Most of the remaining architectural
-work is done and being tested. Then Roland will work on integrating
-cthreads (which is mostly busywork), miscellaneous filesystem calls,
-and then file descriptors. After that comes signals.
-
-Jan Brittenson will be working on the network server library. This is
-a library that, when linked against a BSD protocol stack, will produce
-a Hurd network server. (Such a server implements the socket interface
-in socket.defs.)
-
-
-There are four general tasks that can be done by other people:
-
-1. Completing the existing work on the terminal driver. The existing
-work implements most of the logic you already associate with a Posixy
-terminal driver; it needs the port management and buffering logic
-added.
-
-2. Writing a readline terminal driver. We will want, as an
-alternative to the Posixy terminal driver, a readline type terminal
-driver.
-
-3. Writing miscellaneous shell utilities. Here we need shell
-utilities to create translators, etc. They should have a nice rich
-set of features to do all kinds of GNU things.
-
-4. Writing miscellaneous filesystem servers. Here we need a
-transparent tar server, a transparent FTP server, and the like.
-
-
-Future plans for work to be written by me (once the bootstrap works,
-and in addition to testing library code as Roland finishes it):
-
-o split the existing filesystem into three parts:
- o a library for port management for complicated multi-threaded
- servers;
- o a library for "normal" disk-based filesystems;
- o ufs specific code.
-
-o Write the PF_FILE socket server (what you know as PF_UNIX).
-
-o Finish the posixy terminal driver if nobody else has.
-
-o Write miscellaneous shell utilities that nobody else has.
-
-o Build a self-hosting system.
-
-
-What you need in order to be able to help now:
-
-o A 386 PC running Mach 3.0. If you have some other kind of hardware,
- then you need to port the GNU C library support first. I'm not
- entirely sure how much work that involves; you will need to contact
- Roland. It might be too much trouble at this point to spend any
- effort on it. It's best if it's a machine for which a free port of
- Mach is available, though you could do useful work even if it's not.
-
- If you are not currently running Mach 3.0 with somebody's
- single-server, then it is very unlikely you could help, unless you
- have a Unix source license. In that case, you could talk to CMU
- (write mach@cs.cmu.edu) to find out how to get Mach 3.0 running on
- your machine. It is not possible to do development without a Unix
- emulator of some kind; just bare Mach 3.0 is not sufficient. I have
- neither the time nor knowledge to help someone get a 3.0
- single-server system running.
-
-o Clue. I don't have enough time to explain operating systems or Unix
- to people. You need to have an iron-clad grasp of Unix semantics
- (specificaly BSD); it's essential that things be exactly right from
- that standpoint. It's not enough that you've programmed Unix
- before; you need to understand all the nits. However, you may
- disregard my previous comments about a "two question limit". You do
- need the ability to intuit to some extent, however.
-
-o Time. It's not good for me to delegate a task and then have nothing
- happen on it. If you have a full-time job where you can't justify
- Hurd work as part of your job, you might find that you don't really
- have as much time as you thought. Please make sure you really have
- enough time before volunteering for a task.
-
-o Efficient net access. Without a real Internet connection (mail only
- is not sufficient), it will be impossible for you to do development
- right now.
-
-
-If you think you can help, send me email. If you don't think you can
-help right now, then don't give up: the list of conditions will change
-as the list of delegatable tasks changes.
