Not all of them. For example, network devices don't appear in the filesystem in BSD (although i think this is just inconsistent with the remainder of the OS). Anyway, i've got an implementation for a /dev/rtc in the pipeline, but it went somewhat on the backburner (the ISDN folks are bugging me to adopt the sppp driver for the new isdn4bsd code :). The idea behind /dev/rtc is that you could do synchronized reads from their, correlating to the CMOS RTC ticks. The implementation is 95 % ready, but needs some thoughts to solve a few tricky things on SMP machines. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
