While the stronger compression, and being faster is definitely nice, having portage on squashfs is really nice on ARM devices, however the number of them that have a decently running kernel newer than 3.8 are few and far between, so I'd like to ask that this be held off as long as possible. I know these are just possible improvements, but doing so would definitely alienate a really good place where this would shine. > 2. dedicated SquashFS delta tool -- I'm working on it but > the format seems to be poorly documented so it will take some time :). >
