Tried to debug failure & traced it to subprocess.Popen calling fork_exec()
with a bad path, but couldn't reproduce error from manual debugging
using ``nix-shell``.
Bad path meaning that most paths were of form /nix/store/.../bin/sby,
but one path was "sby" only. That's my only guess as to what would
be causing this failure.
`rngd` seems to be the root cause for slow boot issues, and its functionality is
redundant since kernel v3.17 (2014), which introduced a `krngd` task (in kernel
space) that takes care of pulling in data from hardware RNGs:

Closes: #96067
The build has been broken since gdk-pixbuf-xlib was broken out into a
separate package in #88086.
For some reason if I just add gdk-pixbuf-xlib.dev the headers don't make it
into CFLAGS.
This commit fixes the ejabberd tests for hydra:
mod_http_upload and mod_disco need to be explicitly enabled, and a
handler needs to be setup to make it work. Also, the client needs to be
able to contact the server.
The commit also fixes the situation where http upload failed: in that
case the client would wait forever because nothing catched the error.
Finally, there remains a non-reproducible error where ejabberd server
fails to start with an error like:
format: "Failed to create cookie file '/var/lib/ejabberd/.erlang.cookie': eacces"
(happens ~15%) I tried to check existence of /var/lib/ejabberd/ in
pre-start script and saw nothing that would explain this error, so I
gave up about this error in particular.
On darwin the compilation would fail with the following warning:
```
clang-7: error: argument unused during compilation: '-fno-strict-overflow' [-Werror,-Wunused-command-line-argument]
```
This error happens because the `-fno-strict-overflow` is passed to the compiler. To fix this, disable the `strictoverflow` hardening feature. Also see #39687.
ZHF: #97479
The `pass.withExtensions`-function uses `buildEnv` to create a
derivation which contains a `pass`-package and a list of extensions for
it.
However, this function always uses the `pass`-attribute for `buildEnv` which
will break e.g. `passmenu` or `pass show -c` on desktops using Wayland (and
`pass-wayland.withExtensions`) since the default `pass`-package without
support for Wayland's clipboard is used.
This patch replaces the `pass`-attribute in the derivation with
`pass-wayland` to work around this issue.
