The recommended practice for `.Os` on FreeBSD is to not specify any arguments. The correct OS name is used automatically. Oddly enough, on the Linux distro I tested this on (CentOS 7), the man pager defaulted to displaying "BSD" as the OS rather than "Linux". To accommodate this, tack " Linux" back on in an install hook on Linux. This is much simpler than removing it for FreeBSD when vendored in the base system.

|
