Upgrading context is easy now that I keep it in ~/texmf/, so updates
to the Debian tetex packages don't overwrite or shadow the latest
context.

My worry about upgrading pdf(e)tex is that when I do the next

  apt-get update && apt-get upgrade

then my pdftex 1.30 will get wiped out by the v1.21 that comes with
the slightly updated tetex-3.0.  Then I'll have to regenerate the
context formats (the apt-get upgrade will regenerate only the system
formats, not my own).

Already this overwriting happens with metapost 0.91: After upgrading
the tetex, it gets returned to 0.63 or something like that.  So I keep
the 0.91 install tree around and wrote a Makefile to reinstall it over
the 0.63 version (Taco has put that Makefile in the metapost
distribution).  But I'd like to minimize the amount of homebrew
administration, which is why I keep my hands off pdftex.
