[Bug 40189] Re: autofs needs to be restarted to pick up some shares

Good evening,

I see this bug in Ubuntu 16.04.1 LTS with autofs version 5.1.1-1ubuntu3
when I try to access cifs shares from my NAS.

When I try to access the shares with 'cd' or 'ls' after boot with
network on both sides up and running I got the error message: "File or
Directory not found." After running `sudo systemctl restart
autofs.service` it works like a charme.

Here is my '''/etc/auto.master.d/diskstation.autofs''':
~~~
/home/tronde/diskstation /etc/auto.diskstation
~~~

And my '''/etc/auto.diskstation''':
~~~
music -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/music
photo -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/photo
share -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/share
video -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/video
home -fstype=cifs,uid=1000,gid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/home
~~~

This way autofs has no advantage over the manual mount with mount.cifs.
Open this bug and fix ist, please.

  autofs needs to be restarted to pick up some shares

Bug description:
  I am using autofs to access shares on a Windows XP machine from a
  Kubuntu AMD64 machine.  The problems applies in both Breezy and
  Dapper.

  EDIT:  confirmed with similar configuration on Intrepid with a NetApp
  filer hosting NFS.  Server OS removed from summary.

  When I first try to access the mount point via cd or in Konqueror it
  does not exist.  However,  if I then restart autofs
  (/etc/init.d/autofs restart) everythin then works OK.  My config files
  are:

  auto.master

  #
  # Sample auto.master file
  # This is an automounter map and it has the following format
  # key [ -mount-options-separated-by-comma ] location
  # For details of the format look at autofs(5).
  #/misc	/etc/auto.misc --timeout=60

  /petunia /etc/petunia.misc --timeout=60
