Barry:
I guess I understand what you want: you want to put all tools on AFS
space (that normally would be replicated on all machines if it's a LPP)
and then just link the files from your AFS to your machine.
I'm doing some work on that and I have a version ready for AIX 4 already.
My ideia is to change the executable /usr/sbin/inurest, which function is
to restore the LPP to local disk. The change will cause all directories
to be created in local space but all files to be linked to AFS space. The
space requirements are minimal and you have the following advantages:
-all lpp software is installed on the same way (using smitty)
-all configuration will take place
-the software will be in the ODM
-ptfs can be installed and they will overide the link, so you can
test new ptfs without disrupting other machines. When the ptfs is fine you
can put the ptf in AFS space and keep both version running without using local
disk space.
Currently I'm using this tool to install info, xlc, xldb, xlf, UMS and Wabi
in about 80 machines and didn't have any problem (for info this is great,
because no local disk space is used for the databases).
I don't know what will happen with AIX 3.2 because I didn't have the
chance to test yet, but it should work also.
Let me know if you're insterested and I will send you the scripts with some
docs and limitations.
