- With respect to the question of softlinks: All kpathsea-based systems
  (that's at least TeXLive and its Mac relatives, I don't know about
  MikTeX) support an alias file.  This allows you to load
  amsfoo-renamed.cls if amsfoo.cls is requested.  LaTeX, however, will
  still complain that the wrong package has been loaded *if* the package
  identification in \ProvidesPackage has been changed.

  Therefore, IMHO, the wording of the LPPL does make sense to preserve
  file integrity, but the "Knuth wording" used by AMS does not; the mere
  requirement to change the filename is moot.

- In all systems following the TDS, path does matter, and moving a file
  from $TEXMF/tex/latex/ams/ to $TEXMF/myengine/latex/ams/ will make it
  inaccessible for LaTeX in a usual setup.

So if we'd have to rename directories there would be a problem. I assume that's not AMS' intention.

Renaming files wouldn't be a problem if AMS allows aliases and keeping the package ID. AFAICT, they do in the current wording, but the question is: is that also what they mean?

All in all, since Debian has a special exception to allow software that
requires renaming of modified files, I don't care much whether the
licensor does it "properly" (like using the LPPL) or naively.

I'm not sure I follow this. Does "a special exception" mean: "we kind of think it's not free, but we allow it anyway"? Anyway, probably not relevant to gNewSense.

Regards, Frank
