OK - but then it won't work correctly.
If nothing else, the GETNEXT handling should return
the appropriate OID - not just echo the supplied one.

I'm not sure how robust the pass handler is - it would
tend to assume that the pass script is behaving itself.
.

Either would work - depending on how you write the
pass script.   Registering the OID of the object is
better practise, since it means you can handle
SNMPv2 invalid instance requests correctly
(noSuchInstance rather than noSuchObject).

I presume you've disabled the standard sysDescr
processing first?

Not something I've looked at recently, but you could
try using the "override" token.   Though that would
mean setting the value in the snmpd.conf file itself,
which probably isn't what you want.
  (And could be done using the "sysdescr" token anyway).

The other possibility would be to tweak the relevant code
in 'agent/mibgroup/mibII/system_mib.c'
