Good, all these patches (compression support + archiso2dual -S change) 
are on my "experimental" branch.

Sounds good. What patches are you using? Is not posible/easy to build 
only "sqfslzma" module? (plus a trivial patch for add lzma "as 
supported" in kernel26 package).

(We have a party when we lzma + Val's writable overlays in Linux vanilla :P)

I don't know I never used that.

another workaround can be in Makefile

- mkarchiso -p base create $(WORKDIR)
+ mkarchiso -p $(shell pacman -Sgq base | grep -v ^kernel26$) create

Yes I want this, seems that other people too :)
In these days I am busy, but I can experiment on this in some days.
