The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=9fb276ea800171b2065994b532931eb684777120 commit 9fb276ea800171b2065994b532931eb684777120 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2023-02-02 20:03:28 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-02-02 20:04:05 +0000 kboot: Trim initial allocation to 64MB We only need 64MB to read off ZFS pools. Since Linux doesn't do ovecommit by default, the extra 64MB is 64MB less we can allocate for things like RAM disks.
