To install software on a VAX using the standard INSTALL-procedure
DEC advises to remove all the users from the system.
This is a big inconvenience of you are maintaining a cluster
with over 100 users.
Minor software-upgrades, eg. a new version of the FORTRAN compiler,
can apparently be done during normal time-sharing.
 - But it is not recommended by DEC to do so! -
The upgrading to VMS 4.3 showed that first a lot of work was
done in an alternate system-root (SYSF). This could have been done
with all the users on the system. Only in the final phase
all the software is moved to the main root (SYS0).

          It should be possible to do software installation on a running
          system perhaps in an alternate system-root and then
          reboot your system enabling your newly installed software.

QUESTION: Do you have any hints, comments, remarks concerning
          'software-installation-on-the-fly' ?
