Busybox is very inactive maintained upstream, so I don't expect this
to be fixed any time soon. Let's hope nobody needs it and
disable it, and if it turns out that they do, maybe we can patch out
the obsolete API uses.
Busybox, systemd and coreutils all have priority 10. Busybox binaries
have been observed to shadow systemd and coreutils binaries.
If systemd is used, its binaries should be preferred, as they are aware
of systemd. For instance, the busybox provided `reboot` cannot reboot
NVidia Jetson AGX Xavier, whereas the systemd `reboot` can.
This also gives busybox lower priority than coreutils. Busybox is meant
for embedded systems with limited resources. If busybox and coreutils
coexist, the resources are normally not an issue. Busybox should only
shadow binaries that are known to be deficient.
If anyone wants to prefer busybox (e.g. memory constrained system with
plenty of non-volatile storage), it's up to them to prioritize busybox
manually above coreutils, util-linux and other packages. It's not a
common case.

This commit adds an argument enableAppletSymlinks?true, which can be
set to false in order to turn off CONFIG_INSTALL_APPLET_SYMLINKS by
users if they only want the main busybox binary in their profile.
This is particularly useful when building pkgsStatic.busybox.
The default version (modprobe-small) is missing important features,
and can also be _extremely_ slow (on purpose[1]).
The non-small modprobe implementation doesn't have all features
enabled by default, so by changing implementation we'd be risking
regression. To mitigate that, I've ensured every feature checked for
in modprobe.c is enabled. So unless there's functionality that's
_only_ in modprobe-small, we should be fine.

Our patchShebangs expect coreutils stat instead of busybox stat.
This broke patching the dispatch script. By enabling strict
dependencies and using explicit --host parameter we not only
avoid cross-compiling breackages but also work around this problem.
Signed-off-by: Jörg Thalheim <joerg@thalheim.io>
We can use use `stdenv.hostPlatform.isStatic` instead, and move the
logic per package. The least opionated benefit of this is that it makes
it much easier to replace packages with modified ones, as there is no
longer any issue of overlay order.

Debian has yanked the upstream tarball we use to get default.script. We
could simply bump the version number to get the new tarball, but to
avoid the problem in the future, we should instead fetch it from git.
The udhcpc binary which currently ships as part of the busybox
derivation will by default search for a dispatcher script at the
location /usr/share/udhcpc/default.script.
This commit includes a working default script with udhcpc and updates
the location where udhcpc searches for this script.
The script was taken the script from the udhcpc package in debian
buster. The only changes from that script is to make it use paths from
the nix store and remove the run-time check for /sbin/resolvconf.
It looks like the original comparrision was incorrect:
host platform - system on which the binary will run
target platform - system for which compiler generates code
(used with compilers)
build platform - system on which the build is invoked
see: https://nixos.org/nixpkgs/manual/#sec-cross-platform-parameters
This change allows to cross compile busybox on OS X
Some packages don’t work correctly with pie. Here I disable it for:
- busybox
- linux kernel
- kexectools
I also get rid of the Musl conditional for disabling pie in GCC and
Binutils. Some day we might want to enable PIE without Musl and it
will be useful to have the *just* work with our compiler and linkers.
