This change makes the wrapper script avoid displaying echo area messages
during startup. This helps prevent split second UI glitches early in the
startup process. The messages itself will still be logged and therefore
will not hamper inspection for debugging purposes.
Preserve top-level symlinks such as /lib -> /usr/lib.
This allows nested containers such as Steam's new runtime to remount
/usr if they need to and then run unmodified binaries that reference
e.g. /lib/ld-linux-x86-64.so.2
Before, we would mount the fully resolved host directory at /lib and
thus the dynamic loader would always be the one from the host filesystem.
The reason for this change is simply to avoid the following messages
that are unnecessary and can be confusing (and these messages will be
repeated for each submodule):
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: git branch -m <name>
With this change the behaviour remains unchanged (apart from the
suppressed "warning" in the console output of course) and therefore this
doesn't cause any hashes to change and by default nix-prefetch-git uses
the "fetchgit" branch anyway (branchName can be set to override the
default):
Switched to a new branch 'fetchgit'
For that reason the initial branch name doesn't matter anyway and since
we're not relying on / hardcoding "master" we could simply switch to
"main" (which seems most common nowadays). See [0] for more details on
why this wouldn't break anything.
However, since the initial branch name doesn't matter and to avoid any
additional risks it was "decided" to keep using "master" (s. #113313).

API change:
`cargoParallelTestThreads` suggests that this attribute sets the
number of threads used during tests, while it is actually a boolean
option (use 1 thread or NIX_BUILD_CORES threads). In the hook, this
is replaced by a more canonical name `dontUseCargoParallelTests`.
The directory in the tarball of vendored dependencies contains `name`,
which is by default set to `${pname}-${version}`. This adds an
additional attribute to permit setting the name to something of the
user's choosing.
Since `cargoSha256`/`cargoHash` depend on the name of the directory of
vendored dependencies, `cargoDepsName` can be used to e.g. make the
hash invariant to the package version by setting `cargoDepsName =
pname`.
The previous commit stopped systemd from looking for system units in
/etc/systemd-mutable/system, which was a Dysnomia-specific path.
While this script doesn't seem to be used anywhere inside nixpkgs (also
not in the gone-since #110799 Dysnomia), its fallback mode (when
/etc/systemd/system is read-only) did write units to that
Dysnomia-specific path, which systemd now doesn't look at anymore.
It might be up for another debate on whether systems with read-only
/etc/systemd/system should probably just use /run/systemd/system, and
not some NixOS-specific paths, as such conditions can happen on other
distros too, but let's pick the other NixOS-specific path
/nix/var/nix/profiles/default/lib/systemd/system for now, which is
probably better than a path that surely is never looked at.
