Package: lintian Version: 2.5.67~bpo9+1 Severity: wishlist udevadm can be present on the system but non-functional, due to being inside a chroot for example. It seems that there are two common patterns used in maintainer scripts that correctly handle that situation:
if udevadm control --reload; then … udevadm control --reload || true Could lintian detect the unprotected udevadm call that, with set -e, will cause the maintainer script to fail? (Context: https://bugs.debian.org/890224)
