I am not using any installer.  I develop with your slackware install on a 4gb SD 
card (USB dongle) and when I am ready to roll my stuff together, I do a minimal 
install onto another card with what I need (no development), roll a JFFS2 on my 
Slackware desktop and make sure everything looks perfect then transfer that back 
to the development SD card (ftp/nfs/whatever) and burn it into NAND typically 
while the 4gb SD card is booted.  I roll my own kernel and strip out anything 
but what I essentially need (typically no modules except maybe a future need), 
test booting from the 4gb SD card, then burn to NAND.  I do not use initrd in my 
final installs and then the plug just stands alone like it's supposed to be.

I can fit most stuff into 70mb leaving alot of the 512 NAND free for future.  I 
have compiled qemu and run an Intel slackware on ARM (for proprietary software 
with no ARM counterpart) with the virtual disk in under 40mb.  So that's 110mb 
total.  That leaves room for web server files or a database, etc.
