Hmmm. Instinctively, I'd say no. Installation from disk and tape normally
differ, and the bootable image might very well be different.
Never having used vtserver, nor exactly remembering how it works, I'm not
absolutely certain though.

In the case of RT-11, a bootable tape has the device-specific boot
blocks followed by a number of MDUP.* files. Each MDUP.* file is in
fact a "frozen" image of a RT-11 system with a special version of DUP
memory-resident, along with the appropriate magtape and disk drivers
for doing an installation.

MDUP is a special version of DUP that has had unnecessary parts
stripped out and some minimal PIP-like abilities added in, just enough
to initialize (and in some cases format and/or bad-block-scan) a disk
and copy a minimal set of RT-11 files from tape to disk.

Instructions for doing the incantations appropriate to making a
specific MDUP are in the back of the RT-11 manuals. And they're mostly
(but not completely) correct :-).

Tim.
