Zenoss install guide lastest error - Zenoss 5.0.9

I founded a possible error on lastest zenoss core document ation guide.

This version doesn't support "btrfs" driver any more. But in page 17, says:

"The following sed command changes the value of the SERVICED_FS_TYPE variable from the default,

rsync, to btrfs."

"EXT=$(date +"%j-%H%M%S")

sed -i.${EXT} \

-e 's|^#[^S]*\(SERVICED_FS_TYPE=\).*$|\1btrfs|' \

/etc/default/serviced"

Is this paragraph deprecated right Now it will be RSYNC driver hear or DEVICEMAPPER, I need to know what params are possible in /etc/default/serviced file.

Thanks in advance
