I might have missed the first message here. I had a minor issue with my
mail filter (after moving my mail host last week) and it was right around
the time the second message came in. Are you discussing merging the
books,
or moving to profiled XML to make two targets from one source?

Two targets from one source so we can share those files that are the
same for both books.

What I had in mind is a different indexd.xml for the systemd book along
with a systemd target in the Makefile.  I want to try to prototype this
today in a new branch.  If I get it working I'll commit that branch for
further review.  For file naming, I plan to just append a 'd' to the
different files, ie indexd.xml vs index.xml.

If it works out, it should make the maintenance work for the systemd
version of the book a lot easier.

It should, and avoids adding anything specific for each book directly in
the XML source as proposed here:

The part I had no creative ideas about was the split changelog (ie: having
to put changes in both changelogs), which is why I had ultimately
suggested the above simple changes.

I see what is being suggested, and I did get it to work. What I did was to add an attribute to a tag, for example I added the following to the changelog:

<para revision="systemd">A test</para>

And then I changed the build instructions in the Makefile to:

$(Q)xsltproc --nonet                   \
   --output $(RENDERTMP)/lfs-html2.xml \
   --stringparam profile.revision sysv \
   stylesheets/lfs-xsl/profile.xsl     \
   $(RENDERTMP)/lfs-html.xml

xsltproc --nonet                              \
   --stringparam chunk.quietly $(CHUNK_QUIET) \
   --stringparam rootid "$(ROOT_ID)"          \
   --stringparam base.dir $(BASEDIR)/         \
   stylesheets/lfs-chunked.xsl                \
   $(RENDERTMP)/lfs-html.xml

The book still builds, and the test paragraph is missing. If I change the two instances of sysv above to systemd, then the paragraph prints.

My knowledge of xsl is still pretty weak but here are some references I have been using:

http://www.sagehill.net/docbookxsl/AlternateText.html#ProfileFilter

------

In other areas, I've been able to merge the two books in a bit more cumbersome method than the above. I had to have separate systemd pages for about 30 out of 255 xml files. With the above, I should be able to reduce those 30 separate pages substantially.

For the change log, it appears we just need to add the appropriate revision= to the entries for those that only affect one book.

My goal is to just run 'make' to build the sysv book and 'make systemd' for the other. I think the method may work for BLFS also.
