Although baselayout-2 supports having /bin/sh -> dash, the initscript provided by partimage will not work with this setting, because the script ${FILESDIR}/partimaged.init uses the non-POSIX syntax "&> /dev/null" which on dash is equivalent to "& > /dev/null" (with space!) which has of course a rather different semantic. A simple fix is of course to simply use "> /dev/null 2>&1" instead.
