While I mostly agree, you also hit the power of the freebsd system: you can do something different. In linux if you want PostgreSQL 12+PostGIS 3.0 with xml support and the packages deliver PostgreSQL 12+PostGIS 3.0 without xml you are stuck without xml support as the package systems don't make it easy for lay people to select options. With FreeBSD you get that power if you want it.

It should be easier though.
