I was looking at isdisk and wanted to hurl chunks. This is used by spec_open to determine if we should be allowed to open a disk device when securelevel >= 1. I'd like to propose changing spec_open to simply NEVER allowing the open of a block device, or character device, if a character device has a block device associated with it and eliminate isdisk() in kern_conf entirely. Objections? (p.s. I found this in 2.2.5, haven't checked 3.0 yet to see if it was fixed, if it was, sorry for bothering you).
