I updated my headless build machine from main-n284480-9a9f93bcf1aa to main-n284504-f91464171d61 this morning, but it panicked prior to completing the transition to multi-user mode. Checking https://lists.freebsd.org/archives/dev-commits-src-main/2026-March/040570.h= tml, blame is cast on 914a53570750; further in that thread, kib@ provides a tentative patch (but I have not tested it).
