@DNSB: That's... not actually clear to me.
That there'd be a free space check during the update's *download* OTA, sure, why not.
But I'm concerned with storage issues in the rootfs, not the USB partition
.
And there, the actual installation is basically an unchecked tar call. There's an integrity check *before* the unpack, but that would have no bearing on a storage space issue arising *during* the unpack.
The only thing that would flag such a failure is the lack of an updated revinfo entry in the install log (/usr/local/Kobo/install.log).
It'll happily keep on trucking and try to install the kernel, bootloader & co, even if the unpack screwed up first. (Which, granted, would probably not be *that* problematic, because those don't live in the rootfs).

That said, we currently have quite a bit of leeway in terms of free space there, so I wouldn't worry too much about it, especially given the fact that the only people actually putting stuff in the rootfs ought to know what they're doing in the first place
