Tom,
I can speak only for DB2/CICS/WMQ but I believe our MVS folks choose the same
way. We use zFS for new products.
During product installation we run the following SMPE job.
SET BOUNDARY(CIC310T) .
ZONEEDIT DDDEF .
CHANGE PATH('/usr/lpp/cicsts/cic310'*,
'/smpt/usr/lpp/cicsts/cic310'*) .
ENDZONEEDIT .
So all apply goes to /smpt like /service which points to SMPT.CIC310.ZFSFILE
(VSAM linear dataset)
Then we copy this file like this
COPY DATASET(INCLUDE(SMPT.CIC310.ZFSFILE)) -
RENUNC(SMPT.CIC310.ZFSFILE, -
SYS5.CIC310A.ZFSFILE) -
SHARE -
TOL(ENQF) -
STORCLAS(AA01) -
MGMTCLAS(MSYST000) -
CATALOG -
TGTALLOC(CYL) -
REPLACE
/*
//*
//MOUNT EXEC PGM=IKJEFT01
//SYSPROC DD DISP=SHR,DSN=SYS5.STCSYS.CLIST
// DD DISP=SHR,DSN=SYS4.SPFSYS.CLIST
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
mount FILESYSTEM('SYS5.CIC310A.ZFSFILE') +
mountpoint('/add1') type(zfs) mode(rdwr)
unmount FILESYSTEM('SYS5.CIC310A.ZFSFILE')
mount FILESYSTEM('SYS5.CIC310A.ZFSFILE') +
mountpoint('/usr/lpp/cicsts/cic310') type(zfs) mode(read)
For zFS you need to mount a new zFS as READ/WRITE and then unmount and mount it
again as READ only. Product zFS or HFS are READ only and shared across several
images.
In case of new service we mount it again as
PROFILE MSGID WTPMSG
MOUNT TYPE(zfs) +
MODE(RDWR) +
MOUNTPOINT('/smpt/usr/lpp/cicsts/cic310') +
PARM('AGGRGROW') +
FILESYSTEM('SMPT.CIC310.ZFSFILE')
and then apply the new service. The new zFS will then SYS5.CIC310B.ZFSFILE
in case of a fallback.
Of course you need to create some mostly orphaned directory in you ROOT HFS.
It's a bit easier for HFS.

Subject: Re: Managing /service for SMP/E
Thanks, Eric.
Everything I've seen from IBM simply says to clone your HFS and
mount it at /service, but that is hardly adequate when you have
17 MVS images and can only get a few IPLs per year. We have
several target zones to keep track of, and we may need to apply
service to any of them. Automount is the best solution that I
know to ensure that the correct HFSes are mounted at the
correct mounty points.
I had written about this several years ago in http://tinyurl.com/ajjmc .
