Adds NixOS configuration to configure my base system with all sorts of things,
including - but not limited to - i3, emacs, FF57, connman and so on.
Not all of these things are fully configured yet (especially in the desktop
environment) but I'm hoping to get more of that done in the future.
I needed this to test ACL/xattr removal in
canonicalisePathMetaData(). Might also be useful if you need to build
old Nixpkgs that doesn't have the required patches to remove
setuid/setgid creation.
The worker threads could exit prematurely if they finished processing
all items while the main thread was still adding items. In particular,
this caused hanging nix-store --serve processes in the build farm.
Also, process items from the main thread.
The path /root/.nix-profile is a sym-link to /nix/var/nix/profiles/default. The
latter path, however, works for everyone while the former path works only for
root, so we prefer the public path whenever possible.
I got sick of trying to find the failures in the sea of debug output, so
we now:
- Hide test output unless it fails
- Sprinkle in some simple color
- Pad results for a more tabular look
If Nix is getting a more friendly user interface, we might as well get
a friendlier developer interface, right? :)
It was getting too much like whac-a-mole listing all the retriable error
conditions, so we now retry by default and list the cases where retrying
is almost certainly hopeless.
The installer will error out if a user's shell configuration includes any mention of ~nix-profile~, even if this is in a comment. This change is designed to do the bare minimum to ignore lines beginning with a `#`.
I find the error message 'nix-env --set-flag priority NUMBER PKGNAME'
not as helpful as it could be :
- doesn't share the current priorities
- doesn't say that the command must be run on the already installed
PKGNAME (which is confusing the first time)
- the doc needs careful reading:
"If there are multiple derivations matching a name in args that have the same name (e.g., gcc-3.3.6 and gcc-4.1.1), then the derivation with the highest priority is used."
if one stops reading there, he is screwed. Salvation comes with reading "A derivation can define a priority by declaring the meta.priority attribute. This attribute should be a number, with a higher value denoting a lower priority. The default priority is 0."
To sum it up, lower number wins. I tried to convey this idea in the
message too.
