# == Class: tripleo::glance::nfs_mount
#
# NFS mount for Glance image storage file backend
#
# === Parameters
#
# [*share*]
# NFS share to mount, in 'IP:PATH' format.
#
# [*options*]
# (Optional) NFS mount options. Defaults to
# 'intr,context=system_u:object_r:glance_var_lib_t:s0'
#
# [*edit_fstab*]
# (Optional) Whether to persist the mount info to fstab.
# Defaults to true.
#
# [*fstab_fstype*]
# (Optional) File system type to use in fstab for the mount.
# Defaults to 'nfs4'.
