Not that I can find (not saying it doesn't, but it doesn't have a man page, and a quick `nm` of all of /lib/lib*.a didn't turn anything up).

No, not ptys -- /dev/log for openlog(3).

Which, if it's started from inetd (as in the case of ftpd, and pop3d among others), could be quite often, especially if you're using tcp_wrappers. Granted, if you're running tcp_wrappers, the 1/2 second will become background noise compared to the DNS lookups.
Just out of curiosity, could someone familiar with the SCSI layer comment on how difficult it would be to get a one-to-one mapping between SCSI controller/SCSI ID and major/minor numbers in a non-devfs setup? Or is that absurd considering the limitations on the current major/minor scheme? What I'm thinking of is something along these lines:
sda: cont 0 id 0 sdb: cont 0 id 1 sdc: cont 0 id 2 ... sdg: cont 0 id 8 (skip ID 7 since it's [normally] the card itself) ... sdn: cont 0 id 15 sdm: cont 1 id 0 ...
And to accomodate this, perhaps the SCSI layer would use a 8 bit major and a 24 bit minor? Or am I highly deluded here?
