well, i didn't ask the Fedora installer for 128 byte indoes in 2008 on
the 500 MB small /boot while the 6 GB rootfs has 256 byte while this
setups are surely targeted to last longer than 2038 until someone kills
Fedora with all the shiny new stuff nobody needs

but yes, don't start to spam me about it
