Fixes https://github.com/NixOS/nixpkgs/issues/27996.
Updates instructions for generating hashes passwords for use in a
Mosquitto password file. Using `mosquitto_passwd` to generate these
hashes is a little less convenient, but the results are more likely to
be compatible with the mosquitto daemon.
As far as I can tell, the hashes generated with `mkpassd` did not work
as intended. But this may have been hidden by another bug:
https://github.com/NixOS/nixpkgs/issues/27130.
Note
- the kernel config parser ignores "# foo is unset" comments so they
have no effect; disabling kernel modules would break *everything* and so
is ill-suited for a general-purpose kernel anyway --- the hardened nixos
profile provides a more flexible solution
- removed some overlap with the common config (SECCOMP is *required* by systemd;
YAMA is enabled by default).
- MODIFY_LDT_SYSCALL is guarded by EXPERT on vanilla so setting it to y breaks
the build; fix by making it optional
- restored some original comments which I feel are clearer
Previously a few clumsy shell globs were used to find haddock output, which
broke every time something in `generic-builder.nix` changed.
Use the new `haddockDir` identifier exported by haskell packages.
WIP
If the `hoogle.nix` file wants to have any sane chance of finding haddock
outputs, the packages need to export the haddock folders as an identifier.
A few TODOs still stand, like passing self to the package instead of needing to
pass it to `haddockDir`. Maybe the exported identifier should be integrated into
the fixpoint somehow instead of using `passthru`?
13d6681ce7 crippled it unintentionally.
Also remove the incorrect/non-existing stdenv.i686-linux;
building the bootstrap tools should be a good-enough test anyway.
