[Buildroot] [PATCH v2 0/2] [RFC] Reinstall Targets

[Buildroot] [PATCH v2 0/2] [RFC] Reinstall Targets

[Doug Kehn]

This RFC proposes adding the following targets to pkg-generic.mk:
	<package>-reinstall
	<package>-reinstall-target
	<package>-reinstall-staging
	<package>-reinstall-images
	<package>-reinstall-host

These targets remove the package's .stamp_*_installed file to allow the
reinstall to execute.  The only method I presently know of to reinstall a
package is to make <package>-rebuild.  The proposed targets allow a package
reinstall without, unnecessarily incurring a rebuild of the package.

In addition to allowing a reinstall to staging and/or target output
directories, the proposed targets allow selected packages to be
installed to a different 'target' directory.  For example, I attempt to
keep software updates as small as possible; therefore, I cherry-pick
files to include in the update package.  If I know packages foo and bar
have been updated, the following will install those packages to a
directory that can be further processed to generate the desired update
package.

make TARGET_DIR=${PWD}/update foo-reinstall-target

make TARGET_DIR=${PWD}/update bar-reinstall-target

[Buildroot] [PATCH v2 1/2] pkg-generic.mk: reinstall targets

[Doug Kehn]

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.

This patch is mixing style cleanups with actual new code.
I'm not opposed to the cleanups, except they should be part of a
seoarate patch.

Yann E. MORIN.

I apologize, I did not know that style cleanup needed to be in a
separate patch.  I will resubmit.
