- INET without INET6 - SOFTUPDATES, UFS_ACL, AUDIT, SCTP (left out for embedded devices) - Björn may add INET6 without INET - SCHED_ULE vs. SCHED_4BSD - No vga console/atkbd/psm for embedded devices - CPU_SOEKRIS, CPU_GEODE, CPU_ELAN, NO_SWAPPING for embedded devices - IPSTEALTH, IPSEC, IPSEC_FILTERTUNNEL, IPFILTER, ALTQ for firewalls - probably more I also always specify exactly one CPU type (on i386), know it made a difference in the 386/486/586 era but am not sure how much difference it makes nowadays.
