General
Just like any of the BSDs, NetBSD can be upgraded by grabbing the latest builds and compiling them from the Internet. Below are the steps to perform this.
Using CVS
Here we need to use CVS to download the latest builds.
setenv CVS_RSH ssh setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot cd /usr/src cvs update -rnetbsd-2-0 -Pd cd /usr/xsrc cvs update -rnetbsd-2-0 -Pd
Compiling the Kernel
The kernel needs to be recompiled with the updates.
mkdir /usr/obj ./build.sh tools kernel=GENERIC cd /usr/src/sys/arch/i386/compile/obj/GENERIC make install reboot
Compile and Install
mkdir /usr/build cd /usr/src ./build.sh -U -x -D /usr/build distribution install=/
etcupdate -a
setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot setenv CVS_RSH ssh cd /usr/pkgsrc; cvs update -Pd pkg_chk -u
