Hi. I am working on Hurd documentation as well. I will tell you what I think, and you can decide how much you want to believe it.
First off, I am somewhat blocked by the fact that I need a copy of a copyright disclaimer from my employer. I expect to have this documentation sometime next week or the week after. Since you are your own employer, this will not be a problem for you. I am actually doing some writing for the GRUB manual right now, but I hope to have that completed in a week or so. Okuji Yoshinori is working on improving the GRUB manual, and, since he knows so much more about it than I do, I suspect my little contribution will not be so useful there. However, he has kindly asked me to continue, so I will have a small part to finish, whether it is used or not. Then, I was going to start working on filling out the Reference Manual. There are several places there which have FIXME, or WORKHERE, which need to be filled out. I was also going to try to add some tutorial or explanatory information somewhere, perhaps in the reference manual, or perhaps in some other manual. Of course, I still have to learn enough about the Hurd to write this stuff, so this will take a very long time. I don't have any idea where the Finally, I think there is probably enough difference between system administration of a GNU/Linux system and a Hurd system that it would be good to have a manual for system administrators. I'm not sure what the contents of this manual would be. Someone would have to do some research there. However, I think there is definitely some reason to think about this. For example, the networking chapters in the reference manual concerning networking are only skeletal. There is work enough for seven here. Right now the logical place to put this stuff is in the reference manual. I'm not sure I believe that having it all in one big manual is a good idea, but I don't have a better proposal right now.
