: I disagree. Once scsi_da found the media, it would then somehow need to
: notify devd (i.e. to automount). If both functions are in devd, the
: loop becomes:
:
: while (1) {
: camcontrol tur mydev;
: if (found)
: notify_automount;
: break;
: sleep 3;
: }
This doesn't belong in devd.
Robert has patches to bring new geom entries into the realm of devd.
