In this release, /dev is managed by utility programs that create symbolic links to the real entries in /devices. The programs are:
disks(1M)
tapes(1M)
ports(1M)
devlinks(1M)
You can run a script to create the appropriate links from /dev to /devices. The /dev names have the advantage of being simpler and more familiar, while the /devices names are unique names for the hardware.
