Yes. /bin/sh is standardized; Solaris for some strange reason ship b0rked year-old stuff though (they may need /usr/xpg4/bin/sh -- but that's a different matter). OTOH, init scripts don't need real processing work, so getting them to fly with the rotten Solaris /bin/sh is feasible and should be done. If it works there, it'll most likely work anywhere else as well :-) > Or do they try to explicitly instantiate bash2 (b)? > > -#!/bin/sh > +#!/bin/bash2 > (b) could be risky if there are distros where where /bin/bash2 is not present. It is indeed harmful, it will actually break SuSE and FreeBSD. I know systems that don't have bash at all, but just pdksh...
