I did not find a single small upstream change that fixes it. Let's

…ig-dynamically

Initial netboot configuration for dynamic agent module import

Strongly inspired by the forgejo counterpart[1], for the following
reasons:

* The feature is broken with the current module and crashes on
  authentication with the following stacktrace (with a PAM service
  `gitea` added):

      server # Stack trace of thread 1008:
      server # #0  0x00007f3116917dfb __nptl_setxid (libc.so.6 + 0x8ddfb)

  It only worked after turning off multiple sandbox settings and adding
  `shadow` as supplementary group to `gitea.service`.

  I'm not willing to maintain additional multiple sandbox settings for
  different features, especially given that it was probably not used for
  quite a long time:

  * There was no PR or bugreport about sandboxing issues related to
    PAM.

  * Ever since the module exists, it used the user `gitea`, i.e. it had
    never read-access to `/etc/shadow`.

* Upstream has it disabled by default[2].

If somebody really needs it, it can still be brought back by an overlay
updating `tags` accordingly and modifying the systemd service config.

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
