Actually an UPDATE does NOT bring in the I/O configuration file (usually in
CONFIG.SYS) which needs to reside on LDEV 1.  A subsequent START would fail
as a consequence.

This also explains why an UPDATE CONFIG corrects the problem by depositing
ALL necessary LDEV 1 files in their proper location - including those in
CONFIG.SYS.

Of course, if your SLT tape is not current with respect to your
configuration, you may be facing a whole different set of problems.
