I didn't actually read all of rc.serial (duh) and assumed that it was called by /etc/rc in some fashion :) (Then again, perhaps the comment and the bottom of the file should be at the top..) My complaint was motivated by a hung process in a remote system with a UPS connected. The only thing I could think that was causing it was this.. 66 271 1 0 3 0 924 260 - R+ con- 52:12.04 /usr/local/sbin/apcsmart /dev/cuaa0 I can't kill it, I have now set dtrwait and drainwait to 1 and it still persists, so maybe my problem lies elsewhere. Regardless the comcontrol man page appears incorrect.. It specifies that the default for drainwait is 5 minutes, whereas on my system (RELENG_4) it is 0. Maybe fix the man page? :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 9A8C 569F 685A D928 5140 AE4B 319B 41F4 5D17 FDD5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
