In 14.04, chroot support in upstart is turned off by default, to
enable please boot with "--chroot-sessions" kernel cmdline option
(which is passed to init) see $ man 8 init , for more details. After
that "service mysql start" will work inside the chroot.

However, instead of using chroots I strongly recommend for you to use
lxc container, which is almost as lightweight as chroot, but has extra
protections against affecting the host system and it has fully working
upstart inside.

Title:
  init: support chroots

Status in Release Notes for Ubuntu:
  Fix Released
Status in Upstart:
  Fix Released
Status in “upstart” package in Ubuntu:
  Fix Released
Status in “upstart” source package in Karmic:
  Won't Fix

Bug description:
  Binary package hint: upstart

  $ sudo chroot /media/karmic dpkg --configure -a
  Setting up cups (1.4.1-1) ...
  update-rc.d: warning: /etc/init.d/cups missing LSB information
  update-rc.d: see <http://wiki.debian.org/LSBInitScripts>
  Rather than invoking init scripts through /etc/init.d, use the service(8)
  utility, e.g. service cups start

  Since the script you are attempting to invoke has been converted to an
  Upstart job, you may also use the start(8) utility, e.g. start cups
  start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
  invoke-rc.d: initscript cups, action "start" failed.
  dpkg: error processing cups (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   cups

  
  WORKAROUND: Create an executable /media/karmic/usr/sbin/policy-rc.d with this in it:
  #!/bin/sh
  exit 101
