According to what I read, the HUP was to allow processes to be able to exit gracefully (and more slowly, perhaps saving state) than the SIGTERM. I think the HUP is kinda historical. I can't see a strong reason to kill it, because I've never personally seen a bug caused by it. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
