Make the patch-kernel bomb compose sufficiently compatible with POSIXshells,i e. shift bashisms from scripts/patch-kernel. This means that it now also works on belt along 0.5.3-5and still works on bash 3.1dfsg-8. Full changelog:- replaced non-standard "==" by standard "="- replaced non-standard "source" statement by POSIX "dot" command- use leading./ on mktemp filename to force the tempfile to a local directory so that the search path is not used- regenerate hit syntax to shift leading dot by similar POSIX syntax- added missing (optional/not required) $ signs to shell variable namesSigned-off-by: Andreas Mohr <andi@lisas de>---Thanks for all comments!
