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.
