I see that Debian's krb5 package's README says:
"... To avoid introducing yet another com_err into Debian, I patched the
Kerberos sources to use the e2fsprogs com_err. This required adding a
k5_comerr_glue.c to libkrb5 to implement several functions not included
in the e2fsprogs com_err. This is an abstraction violation.
Fortunately, work is underway to unify all the different versions of
com_err so this can go away in the future."

Sam Hartman, the Debian developer, told me today:
"I believe that current e2fsprogs has a superset of com_err
functionality for all Unix com_err implementations. I believe that
everything besides OpenAFS on Debian is moving towards using it.
"OpenAFS will probably not need to move to this com_err until it starts
building shared libraries."
I see the latest e2fsprogs has latest Heimdal compile_et extensions.
I'd like to start working on a libcom_err package based on this
e2fsprogs-1.35/lib/et/ code. It has the original Student Information
Processing Board of the Massachusetts Institute of Technology copyright
and license (1987, 1988). This license needs to be updated maybe: it
mentioned "without fee", but other files say "any purpose". The KTH code
included is a BSD license. It also has UCB code and some FSF'd tex macros.
Is anyone else interested in this? (And want to package this themselves?)
