The dpkg database is locked, when a given's package postinst is run,
thus one cannot remove packages as part of installation of another
one.
We already have scripts in place to mark old kernels for auto-removal,
however we do not enable autoremoval by default.
Thus it's easier to enable unattended upgrades and set
Unattended-Upgrade::Remove-Unused-Dependencies to true.

Title:
  possible to run out of space on /boot partition when installed using
  auto recipe & full-disk-encryption

Status in “partman-auto-crypto” package in Ubuntu:
  Confirmed
Status in “partman-auto-crypto” source package in Quantal:
  Won't Fix
Status in “partman-auto-crypto” source package in Saucy:
  Confirmed

Bug description:
  When choosing full disk encryption in the quantal version of Ubiquity,
  the resulting /boot partition seems small.

  In my test installation /boot came to 228MB.

  Assuming that each kernel+initrd comes to about 30MB, that doesn't
  leave much space for old kernels/initrds as kernel upgrades pile-up.

  Many users do not know how to clear old kernels. A full /boot will
  mean that no further apt transactions can occur until older kernels
  are removed and the newer kernel installation is completed.  Users
  will then be missing out on security updates, hardware enablements,
  and installing new packages.
