This is likely to fail with the new default cryptsetup cipher of
aes-xts-plain64, as many downstream kernels used in recovery OS (like
TWRP) do not have CRYPTO_XTS set.
Put a minimum version check for postmarketos-ondev in the pmbootstrap
install code and verify it before starting the installation. This avoids
using incompatible versions, similar to the pmaports.cfg version check
we already have. Set the minimum required version to 0.2.0.
Do not pass the arguments to ondev-prepare as command-line arguments in
a specific order, but instead as environment variables. New arguments
will be added in a follow-up patch.
Checkout the aports.git branch for the current channel (e.g.
3.12-stable), before trying to find the APKBUILD.
I had tried to auto-unshallow the git repository earlier, but then the
tags were missing. I decided that it's not worth to provide a migration
path: "pmbootstrap aportgen" is only used by few advanced users (to
maintain the pmaports repo).
This made sense for Alpine's aports.git repository as we were only using
the master branch. But now that we are using more branches, we need the
entire git repository with all its branches cloned.
Add the Alpine mirrordir (e.g. "edge", "v3.12") to the distfile, so
musl-*.apk files of the same version and arch but from different
mirrordirs do not collide.
Let "abuild checksum" download these apks and generate the checksums,
instead of letting apk download them as side-effect of initializing
foreign arch chroots. The latter did not work anymore, because we would
copy the apk file with a glob that may matches the hash of either mirrordir.
Essentially:
glob.glob(f"{args.work}/cache_apk_{arch}/{subpkgname}-{version}.*.apk")[0]
In the context of the on-device installer, I found that calculating this
hash is not trivial, so let's just avoid it here as well.
While at it, order the imports of musl.py alphabetically.
Add initial support for the on-device installer in pmbootstrap. Let
pmbootstrap create a regular split image, then prepare a new installer
rootfs and copy the previously generated rootfs image into the installer
rootfs. Put the installer rootfs into a new image, with reserved space.
There is more to do from here, such as disabling the generation of the
user account when using --ondev. But this requires support in
postmarketos-ondev first, so let's build that iteratively.

Move code that prints flashing information from install_system_image()
to its own function. For the on-device installer, we'll need to call
install_system_image() twice, without printing the flashing information
each time. While at it, add "step" and "steps" parameters.
Prepare for a future patch, that adds reserved space in MiB, by changing
size_boot and size_root from bytes to MB everywhere. This is what we need
most of the time and allows to drop some /1024**2 statements.
Add a "split" argument to the function, instead of using "args.split"
directly. "args.split" is only defined when calling "pmbootstrap install",
but the next patch will add a code path that calls the function from
"pmbootstrap chroot".
Alpine APKBUILDs have the concept of "provider priorities" that affect
the choice of the provider to install when multiple packages provide
a virtual package.
One use case for this is to allow installation of different firmware
versions. bq-paella can run unsigned firmware, therefore you have the
choice between using the original firmware from the manufacturer, or
a slightly newer version from Qualcomm for the Dragonboard 410c.
We add provides="firmware-qcom-msm8916-wcnss" (the "virtual package")
to both firmware-qcom-db410c-wcnss and firmware-bq-picmt-wcnss.
At this point, attempting to install "firmware-qcom-msm8916-wcnss"
would still fail with apk. (Because it does not know which provider
to install.)
To pick a default we can set e.g. provider_priority=100 for
firmware-qcom-db410c-wcnss (the slightly newer version).
In that case, firmware-qcom-db410c-wcnss should be installed by default.
However, the user can choose to do "apk add firmware-bq-picmt-wcnss"
to override the default choice in case of problems. In that case,
the conflicting firmware-qcom-db410c-wcnss will be automatically removed.
At the moment, pmbootstrap does not respect the "provider_priority" at all.
In the above case, it would always install "firmware-bq-picmt-wcnss"
during "pmbootstrap install" since that has the shortest name.
Extend the pmbootstrap code to pick a provider with the highest priority
(if any of the providers has a priority set).
