Hey all, I'm using CentOS 4.4, and want to start doing some work with ACLs (getfacl/setfacl). Unfourtunately, no matter what I do, I get the same error over and over again: setfacl: <filename>: Operation not supported I've tried enabling/disabling the acl and xattr modes on my root partition (the one I'm working on), I've tried moving the file to other directories, rebooting the system after I make the changes... nothing. Right now, the system is set up as follows: /etc/fstab: LABEL=/ / ext3,acl defaults 1 1 % mount /dev/sda5 on / type ext3,acl (rw) ... Should I have a particular kernel module loaded? getfacl seems to work fine, but it may be deferring to the lower-level chmod permissions that are already there. If there is a kernel module to load, I can't tell what it should be, since there are none that have "acl" in their names under /lib/modules/<kernel version>. Please help!
