       BitTorrent is fantastic for Kiwix files like this replica of English Wikipedia with the pictures. You know what's not great for that? Fucking VFAT flash drives, that's what.

       All right, I think this is going to work to store Wikipedia on a fucking VFAT flash drive:set -e: ${usb?} ${user?}b=$usb/wikipedia-zim.img.time truncate -s 2g "$b"{1..20}for i in {1..20}; do sudo losetup "/dev/loop$i" "$b$i"; donesudo time mdadm --create /dev/md0 --level 5 --force --raid-devices=20 /dev/loop{1..20}DANGER time sudo mkfs -t ext4 /dev/md0sudo tune2fs -r 0 /dev/md0sudo mkdir /wikipedia-zimsudo mount /dev/md0 /wikipedia-zim/sudo chown "$user"."$user" /wikipedia-zim/

       By using Linux's software RAID we can span the 37-gigabyte file across 40 2-gigabyte files, thus circumventing VFAT's file size limitation. It's going to be a pain to mount again in the future, though, and I wouldn't trust its failure recovery any further than I could throw an RK05. But it does seem to be working at the moment.

       For what it's worth, it wasn't irretrievably corrupted by shutting down and rebooting, but the unmount never did finish until I yanked out the USB key. Then the system failed to shut down.

       @kragen maybe zipsplit(1) would have been an option

       @ente You have to get the file before you can split it; I don't have space on my disk.

       @kragen hm, right, I forgot that ZIP is much like VFAT and stores the hierarchy at the very end
