The problem is that printf() is used in the strangest parts of the deepest bowels of the kernel, but if a process grabs the console with TIOCCONS, printing something to the console causes the process that grabbed it to be woken up, which is a bad idea if, for instance, printf() was called from within mi_switch() (as is the case for those "microuptime() went backwards" messages). > My examination of what I could find in the lists > seems to indicate that this bug affects more than must xconsole, it also > presents problems during install.

That makes total sense, thanks for the tip. > Warner, does this sound like something that should go into UPDATING? I'm wondering if actually the correct solution might be to have /etc/rc generate host.conf at boot time from the contents of nsswitch.conf. I'll see if I can cook up an awk script to do that.
