commit 0339b24f8d30f92979c4ec5ba2556cd83cce9e98 Author: David E. O'Brien <[email protected]> AuthorDate: 2025-11-08 02:18:13 +0000 Commit: Colin Percival <[email protected]> CommitDate: 2025-11-10 18:54:37 +0000 random: Have RANDOM_PURE_START be a cross-platform source and one that will be with us in the long-term future. (this helps reduce diffs in the future and for down-stream users that trim entropy sources). Also, move deprecated (removed in 16.0) sources to the bottom of the list to reduce changes to 15.x.
