I also moved to DESTDIR installation of all packages long ago. LFS starting
in Chapter 6 and all BLFS packages. I script and log everything, create a
binary (.bz2) package of all the files in each package, then copy DESTDIR
to the actual filesystem. Works for me. I actually have a routine at the
end that compares each file in DESTDIR against all the installed files in
the actual filesystem.

This is probably the best suggestion, and what I had intended on doing,
but wanted to get any other ideas others may have.

Right. Again, this is what I had intended on doing, just wondered if
there was something easier than having to add stuff to my existing

Thanks to everyone who commented (though some of the comments weren't
relevant to my questions, such as using package-users - yuck!) and I'm
right back where I was, but with the knowledge that LFS package
management is in its infancy right now.

I really had no problem, I just want the ability to always define (have
logs on) how a file/directory was created on my system. And since I was
removing old log files of packages that have been updated, some directories
wouldn't show in logs. A very small issue that is fixed using the
suggestions provided by DJ (which was what I had concluded was my only

Some (DJ and Jack Stone) have mentioned they have notes for using
DESTDIR during LFS. I have more than notes, I have actual commands and
scripts that do it - perfectly. In fact, months (years?) ago I offered
these scripts and ideas to the community, but nobody seemed interested.
Perhaps it was because it was reinventing the wheel. I'm not sure if
DIY started doing DESTDIR before or after I did, but regardless, it is
so easy that it would be a snap to put into LFS.
