Hello,
Is it possible to use ipkg to completely upgrade a device that boots off of a CompactFlash card, such as my RouterBoard?

I use ext3 as the filesystem on my router and I have plenty of free space etc. It seems like it would work okay with the possible exception of configuration files potentially getting overwritten, and of course, I'd have to update the kernel partition myself (in the case of the RouterBoard), but that wouldn't be difficult.
