[Buildroot] [PATCH 0/9] fs: cleanups and enhancements (branch yem/fs)

[Yann E. MORIN <yann.morin.1998@free.fr>]

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.
