Re: mkinstallp/installp pre/post run scripts in the wrong order

I am having a strange problem with installp.
The packages I create are running the scripts at the wrong time.
I have been able to duplicate this on AIX 5.2 and 5.3 so I think it is
something I am doing.

Any suggestions?

Here is a snipit of my template file
Unpre-installation Script: /autobuild/rel/AIX/app/opt/unpre_i
echo Running unPre-install
/opt//app/bin/appctl stop

Post-installation Script: /autobuild/rel/AIX/app/opt/post_i
echo Running Post Install
mkdir -m 755 -p /var/app/log

Unpost-installation Script: /autobuild/rel/AIX/app/opt/unpost_i
echo Running Post unpost_i

There are ROOT part, USR part, and SHARE part scripts;
just like there is a inst_root/liblpp.a and a liblpp.a.
On the install the USR part is installed first, then
the ROOT part. On uninstall the ROOT part is done first,
then the USR part.

The USR part scripts are allowed to modify files in the
/usr filesystem. The share part scripts are allowed to
modify files in the /usr/share tree. The ROOT part scripts
are allowed to modify files in the / filesystem, except
for /usr and /usr/share.

The /opt filesystem is a ROOT part filesystem.
For example see:
lslpp -f bos.rte
and notice how /opt comes after:
Path: /etc/objrepos
same with /var, so your post_i has to be ROOT part
(because it creates /var files), your unpre_i has
to be ROOT part (so that it is run first on uninstall),
and your unpost_i has to be ROOT part (so that the
application files all exist).

When debugging installp images I suggest doing:
export INST_DEBUG=yes
installp ...
and you should see tons of output as installp
processes your bff image.
