I have no idea how RSTS/E deals with disks. I was only talking about tapes.

That doesn't sound quite right. RSTS/E treats a boot disk as an installation (kit)
disk if its file system is marked as read-only. (That's the file system flags, not
the drive write protect button). If you boot such a disk, it goes to the installation
dialog rather than the system start dialog. On 7 December 2015 at 14:29, Johnny Billquist

Actually, RSTS/E have some issues with install if the tape isn't write locked. I
thought it was some combo/confusion between TK50 and TK70, but it was the write lock issue

TMSCP tapes. RSTS/E is
more picky than some others, though, if I remember right...
Yes, RSTS/E installs from TMSCP just fine (as can RSX-11/M+); I know
that in simh you can bring up Ultrix-11 3.1 only on TMSCP
(specifically a TK50), at least if you want all of the packages to
install. I've installed RSTS/E 10.1-L from MASSBUS, TS11, TM11, and
TMSCP in my various experimentation with emulation, it really doesn't
care what the tape is as long as your SYSGEN device is consistent. If you boot from tape, you'll also (always) end up
in the installation dialog since the assumption is that the only bootable tapes out there
are install kits.
I have not done any RSTS/E installations myself, so I'm only repeating
what others have reported multiple times. And according to several
people, if the tape isn't write locked, the installation aborts. Google
for it and you'll find several reports about this.
