Title:
  autofs hangs when server unavailable

Status in “nfs-utils” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: nfs-common

  When using autofs in Hardy to automount nfs shares, lengthy hangs
  occur if the target server is not available.  This causes nautilus
  (and the desktop) to hang at login and when opening.  The problem
  seems to originate with changed behaviour of mount.nfs.  When
  attempting to mount a non-existent server export, Gutsy returns in
  about 3 seconds with the "No route to host" message, Hardy takes about
  40 seconds and returns an "internal error".  This results in lengthy
  delays if there are multiple autofs connections to be attempted.
  These behaviours are shown below:
