This doesn't actually update the kernel, just the linux-libre
deblobbing scripts, but it should mean that automatic updaters keep
the deblobbing scripts up to date. So even if deblobbing scripts for
a new kernel version are not available immediately after release, they
should be updated automatically soon enough once available.
update-libre.sh doesn't commit by default so that it can be used as an
updateScript, where I don't think auto-committing is the norm.
The generated commit messages say "linux-libre_latest" rather than
"linux-libre", because even though linux-libre will also be rebuilt,
it's linux-libre_latest that is more likely to need it.
This will turn manylinux support back on by default.
PIP will now do runtime checks against the compatible glibc version to
determine if the current interpreter is compatible with a given
manylinux specification. However it will not check if any of the
required libraries are present.
The motivation here is that we want to support building python packages
with wheels that require manylinux support. There is no real change for
users of source builds as they are still buildings packages from source.
The real noticeable(?) change is that impure usages (e.g. running `pip
install package`) will install manylinux packages that previously
refused to install.
Previously we did claim that we were not compatible with manylinux and
thus they wouldn't be installed at all.
Now impure users will have basically the same situation as before: If
you require some wheel only package it didn't work before and will not
properly work now. Now the program will fail during runtime vs during
installation time.
I think it is a reasonable trade-off since it allows us to install
manylinux packages with nix expressions and enables tools like
poetry2nix.
This should be a net win for users as it allows wheels, that we
previously couldn't really support, to be used.
This allows things like hooks other than postInstall to be passed
through to mkDerivation, which is very useful when customising or
debugging a package.
