Re: [RFC PATCH 0/8] Update chromiumPacakges

Hi all
Here's a nearly-complete(?) attempt at bumping chromiumOSPackages.
Everything under chromiumOSPackages and spectrumPackages builds except crosvm
(and therefore spectrum-vm). I've added platform2 as a dependency (a few rust
crates from there are now used) and bumped the cargoSha256, so the vendor FOD
now builds happily, but the actual `cargo build` fails with:
...
error: the lock file /build/src/platform/crosvm/Cargo.lock needs to be updated but --frozen was passed to prevent this
If you want to try to generate the lock file without accessing the network, use the --offline flag.
I haven't dealt with buildRustPackage before, so I'm not sure if this is a
standard thing that any frequent buildRustPackage user will know how to fix, or
if we're running in to an odd edge-case - emailing it in as-is in the hopes that
it's the former :)
This is not uncommon -- maybe we could have a better error message for
it in Nixpkgs (or maybe we do already and we're just not seeing that in
Spectrum's Nixpkgs, which is by now quite outdated!).  It means that the
Cargo.lock file in the sources doesn't match up with what the Cargo.toml
file (and any Cargo.toml files of local dependencies like things in
platform2) are asking for.  The error message comes from Cargo wanting
to talk to the network to recreate the lockfile.

To fix this, we can regenerate the lockfile with `cargo generate-lockfile',
and then use the cargoPatches attribute to apply a patch that fixes it.

With that changed, and a few new dependencies added, I was able to get
crosvm most of the way through a build (diff below).

The only problem now is that the boot test doesn't work.  I bisected
that to the following crosvm commit:
...
e4cbef4caf66779e5f8734c63fb591c991bf9674 is the first bad commit

tests: enable logging for boot test
The logs are important for diagnosing errors for the boot integration
    testing. This change enables those logs.
But it's bed time for me now, so that's where I'll have to leave it for
tonight.  Maybe you can figure it out. :)

BTW: your patches aren't threaded properly -- they're in response to an
email that was either never sent or never arrived, rather than to this
one.  Just in case you didn't realise -- it's not a big deal and I made
the same mistake just last week. :)

Anyway, here's what I have so far:
