Personally I've never seen a real reason why would this be I would, but I don't know kernel filesystem stuff at all.

For the record, the reason extroot (which is just the name of the package that automates the use of external storage as the rootfs) is using the overlay is that because Felix, and I think Jo, who are the devs who commented on my original patch before I was a developer, wanted me to change it to working that way. (I believe it was so that the behaviour with extroot was the same as with the jffs2 filesystem, but I could be wrong, and I don't want to put words in their mouth, so I'll let them comment). I personally am indifferent as to whether extroot uses an overlay or not, but that's a group decision, not mine to make alone. I think pivot_root is better than chroot for the purposes of running init and in general for avoiding gotchas, but that can be done without an overlay, if that is the consensus. I'd appreciate if any devs who care would comment on the use of overlay vs plain fs, because the use of mini_fo with the ext4 module seems to be problematic, at least on kernel 2.6.35.
