e5cbc2b86b WIP add systemConfiguration "install" command
which copies the init stuff (whatever it is) from store to /persist
instead of making liminix-rebuild have to know what the files are.

This is principally to ease making a system configuration in /mnt or
similar when operating in a rescue/recovery scenario, and we
don't want to liminix-rebuild because it will reboot

This is for MIPS.  I spent a while investigating why the second virtio

success. Use the first one instead.

8798ee9830 partial fix for timeout handling
1) "Unknown transfer id" message was because the local variable "tid"
is not a transfer id, it is a sequence number  - so the check was
actually comparing expected vs actual acknowledged sequence number,
not TID.  It's still a problem if we get the wrong one, but it
indicates a lost packet (so we should resend) not a packet that was
sent from somewhere else.

2) if the ACK packet has not been received, our retry should involve
_resending_ it, not just trying to wait for it again.

3) I have removed the timeout condition for terminating the resend
loop, because in practice (assuming both ends have the same timeout
setting) all it did was ensure that the loop only ran once. The
timeout is supposed to regulate how long we wait for before retrying
(it doesn't do this, we wait indefinitely), not how long we wait for
before giving up.

343d3b6508 writeFennel is writeFennelScript with knobs on
The second parameter is now an options attrset, wherein we will pile
all kinds of cool stuff.

Right now the only cool bit is `mainFunction`, which allows you to
compile a fennel module into a lua script and name the function that
should be executed when the script runs. This makes it easier to
write testable Fennel code, because the test script can require the
module and call stuff in it.

(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
systemconfig (a.k.a "activate") is run from the initramfs. Converting
it from a shell script to an executable means it doesn't depend on
there being a shell in the initramfs

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
