Bash's standard behavior of not propagating non-zero exit codes
through a pipeline is unexpected and almost universally
unwanted. Default to setting `pipefail` for the command being run;
it can still be turned off by prefixing the pipeline with
`set +o pipefail` if needed.
Also, set `errexit` and `nonunset` options to make the first command
of consecutive commands separated by `;` fail, and disallow
dereferencing unset variables respectively.
PHP 7.3 won't be supported by upstream for the entire life cycle of
the 21.11 release.
Also drop the pcre' alias since it isn't needed anymore since we don't
need different pcre versions anymore.
When importing Nixpkgs within Nixpkgs, we should not consider aliases
to ensure we don't rely on them internally.
There are probably more places that need to be converted.
Assert that the PostgreSQL version being deployed is the one used
upstream. Allow the user to override this assertion, since it's not
always possible or preferable to use the recommended one.
Since the update to wlroots 0.13 (e03dde82a7) the default VGA card
isn't supported anymore and we needed to switch to virtio (qxl didn't
work either). However, as it turned out "-vga virtio" (28b8cff301)
broke the test on AArch64. Luckily there's a third option that works on
all three supported platforms: virtio-gpu-pci
According to [0] "This device lacks VGA compatibility mode but is
otherwise identical to the virtio vga device. UEFI firmware can handle
this, and if your guests has drivers too you can use this instead of
virtio-vga. This will reduce the attack surface (no complex VGA
emulation support) and reduce the memory footprint by 8 MB (no pci
memory bar for VGA compatibility). This device can be placed in a PCI
Express slot."
So in the end this seems like the ideal choice :)

The tests timeout on AArch64 (e.g. [0] and [1]), likely because the QEMU
option "-vga virtio" isn't supported there (unfortunately I currently
lack access to an AArch64 system with NixOS to investigate).
This also affects the test for Cage but that one is already limited to
x86_64-linux.

Adds includeStorePaths, allowing the omission of the store paths.
You generally want to leave it on, but tooling may disable this
to insert the store paths more efficiently via other means, such
as bind mounting the host store.
