ItalianoNetBSD upgrade from sources
Yesterday I finally find the time to upgrade wolverine, my NetBSD test
server. I was in the mood to try something new, so I decided to perform
the upgrade starting from sources.
It was really smooth, although it took a lot of time to compile
everything (wolverine is a PIII 500Mhz). Here are the steps performed.
Backup data (/etc):
$ tar zcvf etc-3.0.tar.gz /etc
Prepare the directories (as root):
% mkdir /usr/src
% mkdir /usr/obj
% mkdir -p /usr/builds/i386
% mkdir -p /usr/releases/i386
Change the ownership of those directories to you user.
Get the sources:
$ wget ftp://ftp.NetBSD.org/pub/NetBSD/NetBSD-3.0.2/source/sets/*.tgz
Unpack the sources:
$ for file in *.tgz; do tar zxvf $file -C /; done
Build or update the crosscompiler:
$ cd /usr/src
$ ./build.sh -D /usr/builds/i386 -R /usr/releases/i386 -u -m i386 tools
Crosscompile the kernel:
$ ./build.sh -D /usr/builds/i386 -R /usr/releases/i386 -u -m i386 kernel=GENERIC
Install the new kernel (as root):
% cd /
% mv netbsd netbsd-3.0
% cp /usr/src/sys/arch/i386/compile/obj/GENERIC/netbsd .
Reboot the system.
Crosscompile the userland:
$ build.sh -D /usr/builds/i386/ -R /usr/releases/i386/ -U -u -m i386 build
Install (as root):
% build.sh -D /usr/builds/i386/ -R /usr/releases/i386/ -U -u -m i386 install=/
Review postinstall failed checks and fix things accordingly.
Update /etc (as root):
% /usr/sbin/etcupdate
