One of the warm-fuzzies you get from running a LEAF based firewall like Dachstein is that it’s not a full-blown Linux distribution. You start with just the stuff you need for a firewall, and add other things you want.

But… there can be gotchas. I bumped into the /proc/cmdline limit on kernel params recently, while adding some more LRP packages to my 1.0.2 Dachstein system. You can tell if you’ve got the problem by comparing the LRP= list in your syslinux.cfg file, and what you see when you type

cat /proc/cmdline

If it’s getting truncated, then you’ve got a problem. I fixed the problem by moving the LRP package list out of syslinux.cfg, and into a separate file. Look for the line in /linuxrc that says
ROOTMAP="`sed 's/.*LRP=/1/; s/ .*//1' /proc/cmdline`"
and change it to two lines like this:
pkglist=`cat /boot/etc/lrppkgs.cfg`
ROOTMAP=`echo $pkglist | sed ’s/ /,/g’`
then put your list of LRP packages in /boot/etc/lrppkgs.cfg in a simple list, one per line, no punctuation. Backup root.lrp and boot, and you should see all your packages loading.
