LOL.  I don't want to start a religious war - everyone has their favorite file 
systems.  :)  IMHO 99.9% of any ACL problems with Samba will result from the 
Samba/winbind deployment, not the file system.  Also keep in mind that winbind, 
getfacl and setfacl will be the same binaries regardless of the file system in 
use, so you may not see the little nuances of the file systems.  

Jamie, if your buddy has time, set up three shares on the same Samba server - 
ext3, Reiser & XFS and play with them using real users and data.  I've done 
that at work, and I think the results will be anticlimactic.  

If he is using Samba at home (with only a few users and probably nothing 
special in regards to detailed security policies on directories & files), I'd 
suggest that he use whichever file system he's been using in the past, since in 
my experience there's no real difference in ACL support.

If he's using Samba at work, I'd look at the environment, read the whole 
document, and make a choice from there.  For example, ext3 extended attributes 
are limited to 4KB, where Reiser/XFS can have 64KB. (IMHO You'd need a very 
complex ACL setup to need that).  Remember that the Windows "deny" ACLs aren't 
well supported.  Also note that the document I linked to is dated April 4 2003, 
almost a year old.  There are newer kernels and the file systems get tweaked on 
a regular basis.

Cheers,

James
