Fedora 25 Alpha released today with kernel 4.8rc2 and btrfs-progs 4.6.1.
https://getfedora.org/en/workstation/prerelease/

The top green "Download" button offers GNOME. If you want something
smaller, on the right hand side are netinstall images with the same
kernel and progs, but no GUI. You can choose the Troubleshooting menu,
and then the Rescue a Fedora System option. It boots, and then you're
at a text UI where you can just get to a shell, option 3.

The easiest way to create a USB stick is with dd and it'll boot
practically anything, BIOS, UEFI, even Macs. Not all wireless firmware
is included in these media, if you have a wired connection it'll be
easier to get dmesg and and contents of btrfs check off. If you opt
for the larger image (GNOME), it's a bit easier to get the terminal
output into a file and either scp it to another computer or you can
also use fpaste <filename> and it'll spit back a URL where it uploaded
the text.
