1g and 2g nanobsd upgrade images not being built

[xbipin]

i have noticed from a few days that 1g and 2g nanobsd update images r never built or if built then never appear in the update folder for download or sometimes the builder starts then skips the run for some reason

[jimp]

The builder run has to do 4 continuous complete runs to generate all sizes. If the build process is stopped and restarted, it resets.

Last I saw, there were some changes going on to try building with a more up-to-date set of FreeBSD 8-STABLE sources, which is likely the cause of it being restarted.
