System V pkgadd clone snapshot available

        For those of you who are interested in cloning the System V
pkgadd package installation system, I have made available a snapshot
of our current work in progress on this project in:


        There is documentation or code in various states of
development for the following commands:

                installf, pkgadd, pkgask, pkgchk, pkginfo,
                pkgparam, pkgproto, pkgrm, removef

        and documentation on the "contents" file format.

        Most of the code in this distribution DOES NOT WORK, but it
does have useful man pages and some working programs.  It should be
of interest only to people who want to work on cloning the SysV
packaging system, as opposed to those who just want to use it.
We were hoping to actually use pkgadd format for the upcoming Yggdrasil
release, but I don't think this code will be ready in time, and will
have to wait for the next release.

        I am indebted to Zeyd M. Ben-Halim for his work on
implementing the pkgadd interface.  pkgproto and the pkgproto
man page are from him, and the pointers that he provided on
how things are actually done on other iBCS2 systems and what
related work was going on in the Linux community was invaluable.

1. JFS2 AIX 5.2 snapshot: consistent snapshot for multiple file systems

The AIX 5.2 JFS2 looks promising but it is limited to one file system
at the time as fat as I can understand the documentation. I understand
that multiple file systems can be in snapshot state but how to create
a consistent snapshout when multiple file systems are involved?

When doing a snapshot of one file system, another file system that
will be snapshotted -scripts with a number of snapshots- can change,
it will be snapshotted just "later" compared to the previous file
system in the script and the next to follow (how small the time window
is, there is one). How to make a script with a number of file system
snapshots "atomic" or "suspend" all existing or new processess that
want to access the file systems that will be snapshotted?
