Thank you. Michael and I enjoy this sort of stuff :-).

In answer to a reporter question, Henry Ford said "You can have it in any
color you want, as long as it's black." Boy, was he wrong on this one! If
you ignore history, you are condemned to repeat it. Cinege associated a
directory to a package for his needs. This association is _not_ cast in
stone and is in fact harmful in some situations.
You may think it is silly to put kernel and packages in ROM, for example.
Charles, Lynn, Mike and the gang are working very hard to come up with a
write-protect switch because there is a need for storage capacities larger
than a floppy AND physical protection that CANNOT be tampered with over the
wire. This is a simple situation and it is easy to understand that failure
is not an option.
By formulating the concept of a default store and that of an exclusion list,
here is _what_I_do_today_ : I boot from a CD which gives me all the storage
I need for the job at hand. I define my default store to be on the _floppy_.
So far, so good? Then I have this code snippet as part of the boot sequence:
for pkg in /var/lib/lrpkg/*.list; do
sed -e "/^etc/d" -e "/^[/]etc/d" -e "/^[.][/]etc/d" \
${pkg} > ${pkg}.light
cmp -s ${pkg} ${pkg}.light
if [ $? = 0 ]; then
rm ${pkg}.light
else
echo ${pkg}
mv ${pkg}.light ${pkg}
fi
done
Yes! Every package list that claimed anything in /etc is rewritten! When I
want to backup, I simply remove the write protect tab on the floppy. I can
assure you that it takes a lot of config data to fill 1.6Mb of compressed
space. Further, if the floppy is lost or if something BAD happens, the
machine still boots from the CD: removing the floppy is akin to a master
reset on the memory, not the software. The entire experience is almost
identical to running from ROM. Sharing it will only improve the process. For
example, the enclosure can CREATE on the fly an empty package if the default
store is not specified. See the discussion.img floppy that is idling
somewhere.
I can do this today because the definitions for the default store and the
implicit inclusion list stems from elementary set theory. Understanding
these definitions allow Michael to package his persistent data in
/var/ucd-snmp/snmpd.conf (which is a GOOD choice) and allows me to backup
/etc and /var according to my needs. Neither of us is wright or wrong: we
simply agree on a definition and we can go on about our business.

I understand completely. The process of changing the way something is stored
is usually referred to as a "conversion" and you will provide at a later
date the conversion procedure for your RAM disk. Will you still be
supporting the old LRP patches, eg, will Oxygen 1.9+ support both the old
tar.gz RAM disk and the new gz only RAM disk?

I am not certain I understand everything you wrote there, but I understand
that you would be happy to include additional packages in your repository. I
am correct?
