From 2522fa8ed7e5e4dcec6a39ef8b6de75585dd721a Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Mon, 11 Nov 2013 16:03:29 +0100 Subject: pkg-infra: add user-supplied step-hooks Allow user to supply their own step-hooks by passing a variable on the make command-line: make BR2_INSTRUMENTATION_SCRIPTS=/path/to/my/script This can be useful to run site-specific actions at each step of the build process, such as logging installed, removed or modified files, do sanity checks on installed files... It is possible to call more than one script, by passing a space-separated lists of scripts to call. Signed-off-by: "Yann E.
