Hello All!
This series introduces some cleaups and enhancements to the filesystem
infrastructure.
Most notably, it gets rid of the post-target rules, i.e. rules defined
by filesystems that were to be executed after the image was generated,
in favour of post-gen hooks.
The reason for getting rid of post-target rules is that they were not
really needed, and the way they were used was dubious when dealing with
top-level parallel builds. Also, the sole user for which those rules
were documented to be useful was not even using the filesystem infra.
The series also introduces the concept of a "landing" area for the
target directory.
This landing area is a copy of the currently-known target/ directory,
copy in which all the target-finalize step and hooks are run, leaving
the original target/ directory to contain only what packages have
installed.
Please read the commit log for the final patch for more on that landing
area.
To be noted: patch 8/9 was the beginning of a bigger plan to rework how
images are generated. However, and quite sadly, that bigger plan is now
evading my recollection. It's sad to get old... ;-] Nevertheless, the
patch by itself still makes sense, so I kept it.
Regards,
Yann E. MORIN.
