[Buildroot] [PATCH v3 0/3] [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
