[Bug 1628735] Re: Autofs variables do not work with kernel 4.4.0-38.57

[Christopher Hill]

apport information

** Tags added: apport-collected xenial

** Description changed:

  Autofs supports variables (e.g. $UID, $GID, $HOME, etc), which can be
  used in automounter map files. One may have configuration such as
  "credentials=${HOME}/.authfile,uid=${UID},gid=${GID}".
  
  If accessing the mount as user "foo", this should have the automounter
  take credentials from ~foo/.authfile and mount it as being owned by
  foo:foo.
  
  On kernel 4.4.0-36.55 and earlier this all works as expected.
  
- It no longer works with kernel 4.4.0-38.57 and instead these variables
- are always as user "root".
