IIUC, I guess it'd be okay if VM installed that as a package. I tried to add
f2fs-tools repo likewise fio, I could't find /sbin/mkfs.f2fs, even if it was
installed into bld/sbin/. Instead, bld/sbin/* were copied into xfstests/bin/
in VM, which enables to execute mkfs.f2fs globally through $PATH.

I set up an almost default kvm-xfstests, and I could see:

# ls /sbin/mkfs*
/sbin/mkfs	/sbin/mkfs.cramfs  /sbin/mkfs.ext3  /sbin/mkfs.ext4dev
/sbin/mkfs.bfs	/sbin/mkfs.ext2    /sbin/mkfs.ext4  /sbin/mkfs.minix

# ls /root/xfstests/bin/mkfs.*
/root/xfstests/bin/mkfs.f2fs  /root/xfstests/bin/mkfs.xfs

Let me know, if I'm missing something.

Thanks,
