I have just upgraded a machine with a Mylex DAC hardware RAID controller to
kernel 2.4.2 with devfs.
It seems that /dev/rd is used by both the RAM disk in the kernel and the
Mylex controller!
This is wrong of course, there are two problems, one is the situation of what
happens if you need both Mylex RAID and a RAM disk. The other is the problem
that Mylex devices get treated as ram disks by devfsd which cause an upgrade
to break (the compatibility sym-links are not created correctly).
I believe that the RAM disk should be changed as /dev/rd has been used by
Mylex controllers for a long time. I am willing to submit patches to the
kernel and to devfsd if this suggestion is accepted and someone can suggest a
good directory name for ram-disks (I don't want to have the same problem
again).
