Thank you David and Hugo,

My bad on three counts:
1) My courtesy close seems to have gone missing.
 Sorry and thank you for replying.
2) I, perhaps, should have pointed to
https://wiki.debian.org/SELinux/Setup#Prerequisites
_.28kernel_and_filesystems.29
which gives a better explanation.
3) Made it clear that I wasn't attacking
 XFS, It's my fs of (non /boot) choice
for some years now; I'm exploring SELinux
 (after the recent Linux conf au 2012
talk) and know I have used inode size defaults
 for my xfs init back in the day!

Best

Al.
