Devices are name-based now: edgemaster# ls -l cuaa0 crw-rw---- 1 uucp dialer 28, 128 Nov 18 14:13 cuaa0 edgemaster# mknod newdevice c 28 128 mknod: newdevice: No such file or directory `mknod` is obsoleted for /dev when using devfs, as the device entries are created and destroyed dynamically as devices are detected and removed from the system. If you accidentally delete a device and aren't sure what the major/minor of it was to recreate it, try something like this: edgemaster# rm cuaa0 edgemaster# ls -l cuaa0 ls: cuaa0: No such file or directory edgemaster# devfs rule apply path cuaa0 unhide edgemaster# ls -l cuaa0 crw-rw---- 1 uucp dialer 28, 128 Nov 18 14:13 cuaa0 > to create a device like 'mknod' doing in 4.x. > Another question: > In DP2: I found the disk partition 'd' will be used.

This is still the case in 5.0. However, I am unable to tell you what 'd' used to represent. I am also clueless on this particular detail.
