Are you refering to the maxusers "> 64" warning? I just changed this in -current to 512 users. It's never caused anything more than a warning that can be ignored, but 512 is a more reasonable "max". Actually, the maximum should probably be increased to the maximum that FreeBSD can support given size limits of certain kernel data structures. ...but since I don't what all of the limits are, I can't really pick a real max value. As for ptys, 32 units are fully supported for each of ttyp, q, r, and s, and if you're not using xterms, another 32 ptys each are supported for P, Q, R, and S...for a total of 256 ptys. -DG
