@mikeymike :
to my first questions : it´s clear, that os4 is not intentioned to be a unix box, but things like ssh2, etc. are not really "only unix" anymore. these features are a must have for implementing such a system into an existing network.
for further versions a multiuser file system (afaik mufs is availible) is very important.
documentation : i´d really like to see a documentation to the system like sun (
like this one) does it.
it would be very helpful for developers to have a full documented system. i know that doing a documentation like the one above is nearly impossible in normal time scales, but sth. similar would be nice.
