The operator stuff entered BSD in 4.3BSD. It wasn't in 4.2BSD or earlier MAKEDEV or similar scripts. Unsurprisingly, it's not in 7th edition, nor System III nor 32V. It appears to have been added in Revision *18173* <https://svnweb.freebsd.org/csrg?view=revision&revision=18173> - (view <https://svnweb.freebsd.org/csrg/etc/etc.vax/MAKEDEV?revision=18173&view=markup>) (download <https://svnweb.freebsd.org/csrg/etc/etc.vax/MAKEDEV?revision=18173&view=co>) (annotate <https://svnweb.freebsd.org/csrg/etc/etc.vax/MAKEDEV?annotate=18173>) - [select for diffs] <https://svnweb.freebsd.org/csrg/etc/etc.vax/MAKEDEV?view=log&r1=18173&log_pagestart=0> Modified *Fri Mar 1 16:43:33 1985 UTC* (41 years, 5 months ago) by *ralph* File length: 6627 byte(s) Diff to previous 14082 <https://svnweb.freebsd.org/csrg/etc/etc.vax/MAKEDEV?r1=14082&r2=18173> added klog in standard. changed disks to be mode 640 root operator. between 4.2BSD and 4.3BSD. There's no indication where it came from, or if it was inspired by something else. I don't have good access to UTS sources or systems to check on other than the V7 port.
