Theo added support for devices to be added with specified locations in the
config file, so theoretically it is not needed..
(though I don't know if it will support a device not found, it will definitly
allow you fo force certain device numbers onto certain scsi devices.)
The new code for NetBSD (magnum) has an improved config system, and also
uses the new scsi system, which allows reporbing at run- time
of trhe scsi bus, though the interactions between this code and the
new config stuff have not been examined yet, and run-time reprobing may
not work in early versions..
Finally, The new scsi code for 386BSD,/FreeBSD,(and might work in NetBSD0.9)
is available from Freefall.cdrom.com:~ftp/pub/scsi
it definitly does allow run-time reprobing and I have often added devices
to the quiescent bus on a running system and reprobed to bring them
on-line. It is not guarenteed to fit into NetBSD without work, as I don't
have running NetBSD, though several people have taken it for NetBSD
and none have ever called back to say that it didn't work..
