Re: Order of package removal

  ok, I was missing the point (I thought that the "trouble" was having
  /var/lib/tetex not removed and left empty) but now I see that the
  real trouble is the font-package postrm not finding the /var/lib/tetex

  I don't know what the outcome of the "in which order are scripts
  called", but in any case why don't you (*):

    - have each of the font-packges that will need /var/lib/tetex on
      postrm ship a /var/lib/tetex/<package name>.emtpy file, so that
      "trouble" can never happen.

  or you could just mkdir it if it can't be found...

    (*) this would gain you the confidence that your system is robust
        even if for some odd reason the postrm call order gets garbled,
        even if you checked that is as you spect in 'normal' situations.

  also, if instead of:

> in tetex-base's postinst script,

  you just ship it in the package, dpkg won't remove it if there are
  files there that he knows nothing about and perhaps will even remove
  it by itself when it detects it has become empty (but not sure about
  this, though).
