nfs-utils/0003-nfs-server-generator-handle-noauto-mounts-correctly.patch
Neil Brown 5073990325 - update upstream version from 1.3.4 to 2.1.1
The significant update is that configuration can
  now be read from a central /etc/nfs.conf file, and
  it can include other files such as /etc/sysconfig/nfs
  This means that the old nfs-config.service systemd
  unit is no longer needed.
- /etc/nfs.conf file created to import all sysconfig
  settings except *_OPTIONS directly into running code.
- dropins created to pass *_OPTIONS sysconfig setting to
  the various daemons.
- various specfile improvements, such as using "-D" in
  "install" commands, and adding "verify_permissions".
- "xtab" has not been needed for years and has now been remove.
- sysconfig.nfs updated, particular the ServiceRestart
  declarations have been tuned for systemd units.
- 0003-nfs-server-generator-handle-noauto-mounts-correctly.patch
  Fix the nfs-server-generator so that mounts marked "noauto"
  are not automatically mounted when NFS exported.
  (bsc#1019211)
- 0001-conffile-ignore-empty-environment-variables.patch
  0002-mount-call-setgroups-before-setuid.patch
  Other minor fixes found during testing.
- REMOVED 0001-Make-location-of-nfs-utils_env.sh-configurable.patch
  now included upstream

Subject: [PATCH] nfs-server-generator: handle 'noauto' mounts correctly.
When this code was written the systemd documentation stated
that "RequiresMountsFor" ignored mountpoints marked as "noauto".
Unfortunately this is incorrect. Consquently a filesystem marked
as noauto that is also NFS exported will currently be mounted when
the NFS server is started. This is not what people expect.
So add a check for the noauto flag. If any ancestor of a given
export point has the noauto flag, no RequiresMountsFor will be
generated for that point.
Also skip RequiresMountsFor for exports marked 'mountpoint', as their
absence is, theoretically, already handled by mountd.
