General

Just like any of the BSDs, OpenBSD can be upgraded by grabbing the latest builds and compiling them from the Internet.  Below are the steps to perform this.

Note:  This example uses the sparc64 architecture.  Please be sure to select the appropriate one for your computer.

Using CVS

Here we need to use CVS to download the latest builds.

# # # # #

cd /usr/src cvs -d anoncvs@anoncvs.uk.openbsd.org:/cvs up -Pd make -k cleandir rm -rf /usr/obj/* make obj

# # #

cd /usr/ports cvs -d anoncvs@anoncvs.uk.openbsd.org:/cvs up -Pd make index

# # # # # #

cd /usr/src/etc/mtree install -c -o root -g wheel -m 660 special /etc/mtree install -c -o root -g wheel -m 444 4.4BSD.dist /etc/mtree mtree -qdef /etc/mtree/4.4BSD.dist -p / -u cd /usr/src/etc env DESTDIR=/ make distrib-dirs

Compiling the Kernel

The kernel needs to be recompiled with the updates.

# # # # # # # #

cd /usr/src/sys/arch/sparc64/conf/ config GENERIC cd ../compile/GENERIC make clean && make depend && make cp /bsd /bsd.old cp bsd /bsd chown root:wheel /bsd reboot

Compile and Install the System

# #	cd /usr/src/ make build

# # #

cd /dev cp /usr/src/etc/etc.sparc64/MAKEDEV ./ ./MAKEDEV all

# #	cd /usr/src/usr.sbin/httpd make -f Makefile.bsd-wrapper distribution

Install mergemaster to merge the new files with the old.

# # # #

cd /usr/ports/sysutils/mergemaster make install clean /usr/local/sbin/mergemaster reboot
