Why? Most MCEs on FreeBSD will panic the machine. I would need to go through the MCA code to see what all gets handled elegantly, but I imagine there isn't much. Also, isn't devd for device removal/insertions? This would be using devd for something it isn't intended for. I guess I have "moral objections" to it. What you're really wanting is Solaris's fmd(1m) daemon, which I believe is also tied heavily into Solaris's smf(5) architecture. http://download.oracle.com/docs/cd/E19963-01/html/821-1462/fmd-1m.html -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
