Hmm, I just implemented this and was about to submit a patch - but finally noticed too late that we specify /bin/sh as interpreter. :-( It seems that ash and dash support "local" keyword, but sh as specified in http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html seems to lack this feature. :-( Suggestions? -- Gernot Siemens AG, Corporate Competence Center Embedded Linux
