find out where to run aif-pre.sh (runs on host) (rename to aif-pre.script)
SCRATCH: find out where to run aif-pre.sh (runs on host) (rename to aif-pre.script)
and get a way to insert that and aif-post(.script) from the kernel params, etc.
remember to uncomment the functions in main() when ready to test
INSTEAD: scripts['setup']?

- use sgdisk? scripting (generated by python) for disk partitioning (part types listed at http://www.rodsbooks.com/gdisk/walkthrough.html )
-- actually, might want to use parted --script instead? then we can do percentages. https://www.gnu.org/software/parted/manual/parted.html

parser: make sure to use https://mikeknoop.com/lxml-xxe-exploit/ fix

left off at network config- i think i just have software/packages/etc. next, unless i already did that

convert use of confobj or whatever to maybe be suitable to use webFetch instead. LOTS of duplicated code there.

need to write docs

make sure you call install.scripts or whatever it's called in main()

update aif.xsd for auth stuff in scripts

need to double-check aif.xsd spec for the packaging command- can i specify a single element?
finish up software/packages section

docs:
