You can explore the history of installable world/kernel materials at places matching the pattern: https://artifact.ci.freebsd.org/snapshot/head/r*/arm64/aarch64/* Some r* will exist without having arm64/aarch64 material but having mateirals for other platforms. The * matches a svn revision number. These are from ci.freebsd.org builds, not the announced/released snaphots. These go back a long ways. ci.freebsd.org does not try to build every svn revision. (It does not build that fast relative to svn updating.) I sometimes use these for approximate bisection without building. The https://artifact.ci.freebsd.org/snapshot/head/r*/arm64/aarch64/* materials are compressed tar archives (*.txz) and a MANIFEST file. bsdinstall uses these files, although I've at times done basic testing activities based on just manually expanding the tars. (The materials do not span u-boot or other such and need to have file system(s) to expand into.) (From a different message:) > I hoped for a more mechanical approach.

This applies both to artifact.ci.freebsd.org materials and the announced snapshots put under https://download.freebsd.org/ftp/snapshots/ . === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
