	As stated in the original comment, only "xfs_scrub_all"
depends on /usr, as it depends on /usr/bin/python.

System binaries that might be used to repair problems should, IMO,
reside on /sbin (or /bin) if they don't depend on /usr.


xfs_scrub has no non-root dependencies on my version:
> ldd /sbin/xfs_scrub                                                
  linux-vdso.so.1 (0x00007ffe275d1000)
  libc.so.6 => /lib64/libc.so.6 (0x00007fd1c3561000)
  libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fd1c3342000)
  /lib64/ld-linux-x86-64.so.2 (0x00007fd1c3b32000)


Ideally the same should go for xfs_restore (and dump), xfs.mkfs,
xfs_repair, xfs_admin, maybe xfs_db (hopefully rare), and xfs_irecover.

Please don't _unnecessarily_ move binaries that might be needed for fs repair
onto /usr if possible.   I've found that using 'xfs' for a root 
file system eliminates my need for an indirect boot off of a
ram disk.

xfs has been far more stable and easy to use than indirect methods involving
a separate ramdisk.
