The branch stable/14 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=953142d6baf3f0fcde98da9455f5936f735613fb commit 953142d6baf3f0fcde98da9455f5936f735613fb Author: Colin Percival <cperciva@FreeBSD.org> AuthorDate: 2024-08-31 23:55:06 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2024-09-11 05:28:59 +0000 EC2: Add new "small" AMIs These are the same as the standard "base" images except: * They don't have kernel or world debug symbols, * They don't have FreeBSD tests, * They don't have 32-bit libraries, * They don't have LLDB, * They don't have the Amazon SSM Agent pre-installed, * They don't default to installing the awscli at first boot. This reduces the amount of disk space in use when the EC2 instance finishes booting from ~5 GB to ~1 GB.
