Generally if you have a running NetBSD system you can upgrade it by
dropping on a new kernel, rebooting,
running some quick tests then extracting the matching userland and
running the postinstall script to clean up.
Some potential issues:

- If you are starting from an ancient system using a.out rather than
ELF binaries things get more complicated
- Sometimes on some ports the bootloader interface changes, requiring
upgrade of boot blocks before kernel
- Handling changes to /etc - the postinstall script is very good at
merging in changes, but can get it wrong

Just a quick question - does a -current kernel give the same issue -
eg, from http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201101121500Z/mac68k/
