+The `cp2k/2025.1:v2` uenv provides CP2K with [DLA-Future] support enabled, in the `cp2k-dlaf` view.
 The DLA-Future library is initialized even if you don't [explicitly ask to use it](https://manual.cp2k.org/trunk/technologies/eigensolvers/dlaf.html).
 This can lead to some surprising warnings and failures described below.
