Its installation is no precondition. In Debian it is still not essential or build-essential. Ben gave some helpful informations and detailed explanations in [2]. There he also suggested to have an option to explicitly set the distribution name (see $KDEB_CHANGELOG_DIST variable). Embedded the improvement as suggested by Thorsten (see [3]): "This is suboptimal: if KDEB_CHANGELOG_DIST is defined, lsb_release is not necessary. The following snippet also omits using its output if it fails but still produces any:" Dealing with this issue I learned about "The Colon in the Shell." and possible pitfalls in this area (see [4,5]). Furthermore, refreshed my knowledge about redirecting outputs with the echo command (see [5]). Special thanks to Thorsten, I enjoyed the IRC session with you. Cooked together the snippets of Ben and Thorsten (see [2,3]). Tested against Linux v3.19-rc2. Thanks goes to Alexander, Ben, maximilian and Thorsten for the very vital help.
