Updating OpenBSD Via Source
Grab source from CVS
First Time
For -current:
cd /usr cvs -qd anoncvs@anoncvs.ca.openbsd.org:/cvs get -P src
For -stable:
cd /usr cvs -qd anoncvs@anoncvs.ca.openbsd.org:/cvs get -rOPENBSD_4_5 -P src
Updating
For -current:
cd /usr/src cvs -q up -Pd
For -stable:
cd /usr/src cvs -q up -rOPENBSD_4_5 -Pd
Rebuilding the Kernel
# cd /usr/src/sys/arch/i386/conf # /usr/sbin/config GENERIC # cd /usr/src/sys/arch/i386/compile/GENERIC # make clean && make depend && make
Rebooting with the new kernel
# cd /usr/src/sys/arch/i386/compile/GENERIC # make install (Safely install new kernel) # reboot
Rebuilding the userland binaries
# rm -rf /usr/obj/* # cd /usr/src # make obj # cd /usr/src/etc && env DESTDIR=/ make distrib-dirs # cd /usr/src # make build
Updating Ports Via CVS
First Time
For -current:
# cd /usr # cvs -qd anoncvs@anoncvs.ca.openbsd.org:/cvs get -P ports
For -stable:
# cd /usr # cvs -qd anoncvs@anoncvs.ca.openbsd.org:/cvs get -rOPENBSD_4_5 -P ports
Updating
For -current:
# cd /usr/ports # cvs -q up -Pd
For -stable:
# cd /usr/ports # cvs -q up -rOPENBSD_4_5 -Pd
Hardware Sensors
Check hardware sensors
# sysctl -a | grep "hw.sensors"
