0312f7a999 fennelrepl look for .fnl before .lua 
this means fennelrepl in nix-shell will prefer local
source files to generated lua files, making it easier
to change library code without restarting the shell

12e25722fa odhcp-script: delete stale dirs from previous runs 
This requires adding LFS as a dependency because native Lua has
no way to iterate a directory, but it seems to be Not Huge and
hopefully we'll have other uses for it

fbb2c04132 move module-based-service parameter types into service 
This is in preparation for writing something that extracts them
into documentation.

user configurations now call config.system.service.foo.build { ...params }
instead of config.system.service.foo

the parameter type definitions themselves now move into the
config stanza of the module referencing the service

new helper function  liminix.callService

The only service moved so far is dnsmasq

69e6eb5a89 accept attr args to pppoe service, and typecheck them 
We use (abuse, arguably) the nixos module system for typechecking.  Un
the plus side, it gives us documentation of the options and their
expected types. On the downside, the error message doesn't tell us
the file in which the error was encountered.

(This is subject to change, if I can find a better way)

c3bb33c9ce add fennelrepl package 
Runs fennel using a Lua compiled with the same options as the
host system, and with packages set up so it can find all the local
Lua packages

To shorten the dev feedback loop further, allows FENNEL_PATH to be set
on the command line so you can point directly it at the Fennel sources
for some library you're working against instead of having to run
nix-build and compile them to Lua

3900683413 simplify protocol for watchers of service output directories 
Previously: the service wrote a timestamp and the receiver
read and parsed it to see if there was new data

Now: the service writes and removes a .lock file to prevent
the receiver reading partial data. The receiver is responsible
for remembering the *previous* state and only updating if it's changed

00aeb81811 min-list-garbage: check all store paths against file 
this is step 1 of min-collect-garbage, no point implementing
deletion ourselves when rm -r exists

(arguably no point in implementing any of it, but this is the bit we
can't do efficiently in bourne shell - it means we're reading the
store-paths list once instead of grepping it afresh for every entry in
/nix/store/)

5dd0c6e3c0 rewrite preinit as very small C program 
By using the kernel "nolibc" header to avoid requiring a C library, we
can bring the initramfs size to around 4k

This does involve a tiny bit of inline mips assembly which I'm not
sure about. gcc seems unwilling to generate the code to load $gp at
function entry of main(), so we do it by hand - but I'd rather find
out why gcc doesn't.

1cc0b13b57 rewrite systemconfig in C and link statically

54a1ab3529 support jffs2, with initramfs 
the jffs2 filesystem contains only /nix/store and a script which is
run in early init (initramfs) and is responsible for recreating
"traditional" directories (/bin /etc/**/* /var &c) based on the
configuration.

this is tested only in qemu so far and could use some cleanup

not having to copy all the desired store paths into a
single directory just so we can create an image from them
