That's because you don't properly understand what the process is doing. Does the cron process give you the heebee-jeebies? What about the "scary" ones like vmdaemon, pagedaemon, syncer, and swapper? Come on, think with your head. > Doesn't the word "cron" pop into everyones head when someone says "I'd like > to > run something once every X timeunits". Cron has uses for some things, but not for all things. Also, this change is much less painless to a) other MTA's, and b) to sysinstall and descedants as the only change is to sendmail_flags in rc.conf, rather than having to try to automate editing of files. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
