SLAX挂载模块的顺序问题？

slax是把所有模块排序后载入，还是先加载slax下所有模块，再加载slax/modules下的模块，我一直感觉是前者，但是从init脚本上看似乎是后者。附脚本内容：
union_append_bundles() #"$DATA" "$BUNDLES" "$UNION"
{
debug_log "union_append_bundles" "$*"
local BUN
echo_green_star
echo "Adding bundles to union"
( ls -1 "$1" | sort -n ; cd "$1" ; find modules/ 2>/dev/null | sortmod | filter_load) | grep '[.]'$BEXT'$' | filter_noload | while read BUNDLE; do
echo "* $BUNDLE"
BUN="$(basename "$BUNDLE")"
mkdir -p "$2/$BUN"
mount -o loop -t squashfs "$1/$BUNDLE" "$2/$BUN"
mount -o remount,add:1:"$2/$BUN" aufs "$3"
done
}
# sort modules by number even if they are in subdirectory
#
sortmod()
{
cat - | sed -r "s,(.*/(.*)),\\2:\\1," | sort -n | cut -d : -f 2-
}
