o To my knowledge, the "//DD:..." construct is not documented as
a facility of /bin/cp. It may happen to work in some cases,
but if it produces unexpected or undesired results, it won't
be supported.
o ISTR bad APF entanglements with BPXBATSL:
#BPXBATR.1 "z/OS V1R7.0 UNIX System Services Command Reference"
... Failure to meet the
following conditions will result in a failure when BPXBATSL is invoked.
...
* The invoker must have an UID of 0 to issue a SH request
* The child process is not setuid or setgid to a value different from
the parent
* The spawned filename is not an external link or a sticky bit file
* The parent has enough resources to allow the child process to reside
in the same address space
One or more of these have tripped me up in the past.
