Thinking back on all the breaking changes I've dealt with since 2010: 32-bit Linux distros discontinued, SMB incompatible between Windows versions (and samba versions) without tweaks, root encryption certificates added/removed, OpenSSL requiring all SSH keys manually updated: This NetBSD machine may have been running for all that time, but no way was it unmanaged. Some Morlock was turning the cranks and oiling the gears.
