I use batch queues too.  (I have two single-threaded batch queues for this,
so I "sort of" have parallel startup...  i.e., any jobs that are
dependant on order (i.e., tcp/ip, mx, uucp, etc.) get submitted IN order
to a specific queue).

Another side benefit of this is kind of having a "minimum" startup
if I need to.  I.e., i may not necessarily want p1 set to 'MINIMUM',
but I certainly have the option of stopping the batch queue(s) right
away if I want to prevent further startup.

I haven't had the time to seriously investigate the SYSMAN startup
procedures (mostly because I don't see the NEED.  Our system
is a single large system.  If I was in a huge cluster, I'd probably
more seriously consider the SYSMAN stuff...)

I wonder what's next...  SYSTARTUP_v6?   :-)

ditto.  (about the only thing I do DIRECTLY in SYSTARTUP is mount
my disks, define logical names, and then fire off all the other
batch jobs).   "works for me".
