[Buildroot] [PATCH v3 1/3] pkg-generic.mk: reinstall targets

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

Doug, All,

Sorry to come back to this so late...

On 2014-11-28 09:25 -0600, Doug Kehn spake thusly:
> Add reinstall targets for host, target, staging, and images variants.
> clean-for-reinstall targets added to remove package
> .stamp_target_install file to allow package install.  Additionally, when
> OVERRIDE_SRCDIR is provided, .stamp_rsynced is removed to ensure pakcage
> is up to date before reinstalling.

Indentation here (and in other places in that file) is off, but that's
not your fault: the existing code is already borked.

I am not very happy with the fact that we add new actions here; the rest
of the code block is so far only concerned about ordering, not the
actual commands to execute.

The only other similar make target that removes stuff is the
$(1)-dirclean target, that uses a fake stamp-file (that it actually does
not touch) to actually does the cleanup.

I agree this is a bit convoluted, but I'd prefer we keep the current
layout: the code around here gets concerned about ordering, and we
actually implement the rules above (around line 248-250), using a fake
stamp file (obviously, one for each new -reinstall target).

Are you still interested in this? Would you mind looking at that?

Again, sorry for the delay in reviewing this series... :-/

Regards,
Yann E. MORIN.
