Currently, grub-mkstandalone includes all modules in memdisk. It would be nice to be able to include only the specified modules, with automatic dependency resolution.

It is not hard to do even in a wrapper script, without access to dependency resolution routines. I do something like this before invoking grub-mkimage ($moddir is a temporary directory for building memdisk, $mods is the list of modules):

# Iteratively include all dependent modules
local oldmods= deps= modname=
while [ "${mods}" != "${oldmods}" ]; do
for modname in ${mods}; do
deps=`sed -n "s/^${modname}://p" ${libdir}/${arch}/moddep.lst`

mods=`echo ${mods} | tr ' ' '\n' | sort -u`

# Filter filesystems list, so that "search" doesn't try to load modules
# Filter commands from minicmd overrides
mkdir -p ${moddir}
cp -p ${libdir}/${arch}/*.lst ${moddir}
sed -ri "/^(`echo ${mods} | tr ' ' '|'`)\$/b; d" ${moddir}/fs.lst
sed -ri '/^\*(cat|help):/d' ${moddir}/command.lst

mods=`echo "${mods}" | sed "s:.*:${libdir}/${arch}/&.mod:"`
cp -p ${mods} ${moddir}

Filtering command.lst above is only necessary if "cat" or "help" are not separately included. Perhaps requiring such filtering can be classified as a bug instead.
