flashrd creates OpenBSD images tailored for embedded hardware devices and for executing from a virtualized environment. It installs a complete OpenBSD system with "one-touch" upgrade capability. It boots from a ramdisk to make in-place upgrades easy and complete. flashrd partitions for read-only operation by default, to minimize flash wear.
NSH is a CLI intended for OpenBSD-based network appliances. It replaces ifconfig, sysctl, and route with its own simple command language, and consolidates configuration for other daemons into one place, effectively replacing /etc/netstart and parts of /etc/rc for appliance-style usage. NSH presents the user with a vaguely Cisco-like interface with all configuration in one easy to read text list. It also gives the user access to system information and diagnostics. NSH replaces the userland commands that handle these functions, and talks directly to the OpenBSD kernel or control utility for daemon functionality. Supported external utilities: pf, ospfd, ospf6d, bgpd, ripd, ldpd, relayd, ipsecctl, iked, rtadvd, dvmrpd, sasyncd, dhcpd, snmpd, sshd, ntpd, ifstated, tftp-proxy, ftp-proxy, tftpd, npppd, resolv.conf, inetd, smtpd, ldapd, and ifstated.
