Unknown FreeBSD branch ${branch}!
FreeBSD branches normally look like one of:
* `release/<major>.<minor>.0` for tagged releases without security updates
* `releng/<major>.<minor>` for release update branches with security updates
* `stable/<major>` for stable versions working towards the next minor release
* `main` for the latest development version
Branches can be selected by overriding the `branch` attribute on the freebsd package set.
'';
# `./package-set.nix` should never know the name of the package set we
# are constructing; just this function is allowed to know that. This
# is why we:
#
# - do the splicing for cross compilation here
#
# - construct the *anonymized* `buildFreebsd` attribute to be passed
# to `./package-set.nix`.
callFreeBSDWithAttrs =
extraArgs:
let
# we do not include the branch in the splice here because the branch
# parameter to this file will only ever take on one value - more values
# are provided through overrides.
