Or else `services.udev.packages = [ bcache-tools ]` cannot be used.
To not break bcache in the initrd I'm modifying this in stage-1.nix:
- --replace /bin/sh ${extraUtils}/bin/sh
+ --replace ${bash}/bin/sh ${extraUtils}/bin/sh
Reasoning behind that change:
* If not modifying the /bin/sh pattern in any way, it will also match
${bash}/bin/sh, creating a broken path like
/nix/store/HASH-bash/nix/store/HASH-bash/bin/sh in the udev rule file.
* The addition of /bin/sh was done in 775f381a9e34
("stage-1: add bcache support"). It seems somewhat plausible that
no new users have appeared since then and we can take this opportunity
to back out of this change without much fear of regressions.
If there _are_ regressions, they should be in the form of build time
errors, not runtime (boot), due to how the udev rule output is checked
for invalid path references. So low risk, IMHO.
* An alternative approach could be to copy the /bin/sh substitute rule
over to the non-initrd udev rules implementation in NixOS, but I think
this way is better:
- The rules file comes with a working path out of the box.
- We can use more precise pattern matching when modifying the udev
rules for the initrd.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-17.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-17.03
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
