Here is the fstab entry on a working 12.04:

Hmm, this is interesting, this is what I have in my /etc/fstab on
Ubuntu 12.04 server
# /etc/fstab: static file system information.
# / was on /dev/sda1 during installation
UUID=63c10807-be9a-4aed-bf2f-fa52e53fc162 / ext4
errors=remount-ro 0 1
# /home was on /dev/sda6 during installation
UUID=3826e336-978b-43e6-b02f-83694b132ed3 /home ext4
defaults 0 2
cat /proc/mounts
Shows:
/dev/disk/by-uuid/63c10807-be9a-4aed-bf2f-fa52e53fc162 / ext4
rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered 0 0
/dev/sda6 /home ext4 rw,relatime,user_xattr,barrier=1,data=ordered 0 0
This passes the acl test on
https://wiki.samba.org/index.php/Samba4/HOWTO even though acl is not
mentioned (it is installed) and Samba4 from git compiles and
installs ok.
Do I need to add acl to my /etc/fstab lines? user_xattr seems to be
a default setting.

Hi Rowland
My Samba4 is installed at /usr/local/bin on the / partition of the
disk so I added acl,user_xattr to the / line in fstab and rebuilt
with libacl1-dev installed, having read a post on the Ubuntu forum.
Before this, I had the same s3fs error when provisioning.
/proc/mounts here gives the same output as yours so It looks as if
the acl parameter is not needed, but no harm in trying. Are you able
to reboot if you change fstab? If my memory server me correctly,
remounting didn't work.
Sorry can't be more positive.
Cheers,
Steve
Well, I could try adding acl to the relevant /etc/fstab lines but as I
said Samba4 compiled, installed & provisioned without complaining
about it being missing. The acl test from the howto was passed on the
relevant partitions, so I am wondering if I do need to alter my
/etc/fstab.
Is there anybody out there, with more knowledge than me, who can
confirm one way or the other?
Rowland
Well, after a bit of thought and downloading the kernel source from
Ubuntu, I am answering my own question.
This is from the source file for the kernel that Ubuntu 12.04 uses
(3.2.0-25)
It comes from "Documentation/filesystems/ext4.txt"
nouser_xattr Disables Extended User Attributes. If you have extended
attribute support enabled in the kernel
configuration
(CONFIG_EXT4_FS_XATTR), extended attribute
support
is enabled by default on mount. See the
attr(5) manual
page and http://acl.bestbits.at/ for more
information
about extended attributes.
noacl This option disables POSIX Access Control List
support. If ACL support is enabled in the
kernel
configuration (CONFIG_EXT4_FS_POSIX_ACL),
ACL is
enabled by default on mount. See the acl(5)
manual
page and http://acl.bestbits.at/ for more
information
about acl.
If I run:
cat /boot/config-3.2.0-25-generic | grep CONFIG_EXT4
I get:
CONFIG_EXT4_FS=y
CONFIG_EXT4_FS_XATTR=y
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y
# CONFIG_EXT4_DEBUG is not set
I would suggest that, as I thought, you do not have to add anything to
/etc/fstab to get acl's, in fact you have to add something to turn them off.
