If the hardware did have change notification, is there a mechanism that would communicate that to geom? That's a precursor question to my real question: is there a way to manually kick geom when necessary? If the api exists but there's no userland app to make the needed calls, I'll write some code -- just point me at a manpage or header file. -- Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
