Not much of VM when I looked late last year. But it sure ain't unix by any
stretch of the imagination.
though the box I saw was running ftpd, TCP/IP (plus Lanserver) and the
usual MVS junk.
For an MVS (including OS/390) program to have equivalent of root privilege
it has to compe from a specified authorised program library AND be
link-edited with the AC attribute.
Unless mandated by RACF or equivalent security software, anyone can run
it
(but it usually IS controlled by such software).
The MVS security model is one I'd dearly like to see in Linux.
