dhall-json 1.2.0 requires dhall's version to be at least 1.14.0 and less
than 1.15.0.  The package wasn't building for me because `dhall` is at
version 1.11.1; pinning to `dhall_1_14_0` fixed it.
The stable build for `yabar` is currently broken: https://hydra.nixos.org/build/75989172

Main reason is that the inline function `ya_setup_prefix_suffix` is
supposed to be an inline function, but was insufficiently declared as
such which broke the compiler recently with the following message:

```
gcc -std=c99 -Iinclude -pedantic -Wall -Os `pkg-config --cflags pango pangocairo libconfig` -DVERSION=\"0.4.0\" -D_POSIX_C_SOURCE=199309L -DYA_INTERNAL -DYA_DYN_COL -DYA_ENV_VARS -DYA_INTERNAL_EWMH  -c -o src/intern_blks/ya_intern.o src/intern_blks/ya_intern.c

collect2: error: ld returned 1 exit status
make: *** [Makefile:18: yabar] Error 1
```

This issue has been fixed on master (see
geokb/yabar@9779a5e)
which is why `nixos.yabar-unstable` remained functional.
`fuck` should only be used for interactive sessions, but nothing more
(so init files like `/etc/zshenv` become even more lightweight).
nixos/thefuck: move init scripts to `programs.*.interactiveShellInit`
This is a temporary hack to fix channel until we resolve #42324.

fluent-bit 3.2.7, 3.2.8 and 3.2.9 are segfaulting when
used in combination with the systemd input. Lets
revert to 3.2.6 for now.

Upstream bug: fluent/fluent-bit#10139

Note that fluent-bit-3.2.7 fixes two high CVEs which we are now
reintroducing. However they are only exploitable if you are
using the OpenTelemetry input or the Prometheus Remote Write input.

OpenTelemetry input: [CVE-2024-50609](https://nvd.nist.gov/vuln/detail/CVE-2024-50609)
Prometheus Remote Write input: [CVE-2024-50608](https://nvd.nist.gov/vuln/detail/CVE-2024-50608)

The problem is as follows:

3.2.7 started vendoring a copy of `libzstd` in tree and statically
linking against it. Also, the fluent-bit binary exports the symbols
of static libraries it links against.

This is a problem because `libzstd` gets `dlopen()`ed by `libsystemd`
when enumerating the journal (as journal logs are zstd compressed). and `libzstd` in Nixpkgs is built
with `-DZSTD_LEGACY_SUPPORT=0` which causes `struct ZSTD_DCtx` to be 16
bytes smaller than without this flag https://github.com/facebook/zstd/blob/dev/lib/decompress/zstd_decompress_internal.h#L183-L187

`libsystemd` calls [`sym_ZSTD_createDCtx()`](https://github.com/systemd/systemd/blob/1e79a2923364b65fc9f347884dd5b9b2087f6e32/src/basic/compress.c#L480)
which calls the function pointer returned by `dlsym()` which is calling into
the `libzstd` that comes with `nixpkgs` and thus allocates a struct that is 16 bytes smaller.

Later then `sym_ZSTD_freeDCtx()` is called. However because fluent-bit
has `zstd` in its global symbol table, any functions that `sym_ZSTD_freeDCtx()`
calls will be calls to the functions in the vendored fluent-bit version of the library
which expects the larger struct. This then causes enough heap corruption to cause
a segfault.

E.g. the subsequent calls to `ZSTD_clearDict(dctx)` and `ZSTD_customFree(dctx->inBuff)`
in https://github.com/facebook/zstd/blob/dev/lib/decompress/zstd_decompress.c#L324
will be working on a struct that is 16 bytes smaller than the one that was allocated
by `libsystemd` and will cause a segfault at some point and thus are probably modifying
pieces of memory that they shouldn't
