A kernel compiled with a number of features Fedora usually lacks, such as disk controllers and most filesystems built-in, root over NFS, USB gadgets, forced module unloading and loading, module versioning, in-kernel memtest, Android APIs such as binder and ashmem to add ease of use for the "Anbox" android chroot, page poisoning enabled by default for security, much more. Works good without an initramfs.
