The attached patch contains a few patches against udev, to remove use of various XSI:isms and bash:isms, and to change two scripts form /bin/bash to /bin/sh. None of the bash-scripts in test/ uses any bash-specific functions as far as I know, but I didn't touch them since they aren't used runtime. Rationale: * Both of the /bin/bash-scripts are totally free from bashisms, hence they don't need to be /bin/bash; using /bin/sh instead helps (mainly) embedded-people * local and source are bash:isms (well, they exist in several other shells as well, but they aren't part of POSIX or any of its extensions) * -a in tests is an XSI-extension, not part of strict POSIX, and is easily replaced by && | http://www.opengroup.org/onlinepubs/009695399/utilities/test.html * Use of fgrep is deprecated in POSIX in favour of grep -F (though fgrep will remain in use for a long time...) | http://www.opengroup.org/onlinepubs/009695399/utilities/grep.html The fgrep-change isn't really necessary, since fgrep can always be implemented as a shell-script, but the rest of the changes would really be appreciated.
