This URL was useful although his manual pages seem to have disappeared.

It wasn't too hard to get it working once I plucked up courage and
overcame sloth.   The kernel patches are included in the standard Gentoo
kernel and I also had to emerge sys-apps/acl.

Two points worth noting:

1.  make menuconfig needed the following turned on in File Systems:

mail root # grep 'XATTR\|POSIX_ACL' /usr/src/linux/.config
CONFIG_FS_POSIX_ACL=y
CONFIG_EXT3_FS_XATTR=y
# CONFIG_EXT3_FS_XATTR_SHARING is not set
# CONFIG_EXT3_FS_XATTR_USER is not set
# CONFIG_EXT3_FS_XATTR_TRUSTED is not set
CONFIG_EXT3_FS_POSIX_ACL=y
CONFIG_EXT2_FS_XATTR=y
# CONFIG_EXT2_FS_XATTR_SHARING is not set
# CONFIG_EXT2_FS_XATTR_USER is not set
# CONFIG_EXT2_FS_XATTR_TRUSTED is not set
CONFIG_EXT2_FS_POSIX_ACL=y
CONFIG_FS_POSIX_ACL=y

2.  this was needed in /etc/fstab (I stumbled across it in the Gentoo
forum):-

/dev/hda2 /home ext3 noatime,acl 0 0
