package_deb: skip pre/postrm scripts on upgrade, write only one shebang
PATCH 1/1 package_deb: skip pre/postrm scripts on upgrade, write only one shebang
From: Andreas Oberritter <[email protected]>
Trying to upgrade busybox removing symlinks but update-alternatives need these links (sed, cut, tail, etc) in order to work.
Adding test to avoid this scripts on upgrade fix the problem, same solution are found in package_rpm class.
