AIX client - mount FS "true" in filesystems

I try to mount NFS on AIX and save attribute "mount = true" in /etc/filesystems, so after reboot my NFS will be started automatically.
I can not find any reference to this option in documentation.

current mount block is
mount '/nfs/disk' do
device '1xx.xx.xx.xx:/vol/nfs/disk'
fstype 'nfs'
options 'rw'
action [:mount, :enable]
ignore_failure true

Mount is working OK but in /etc/filesystems define as "mount = false"

can someone assist?
