Yes, I guess that would be true.  But at least you'd know (if the script 
is found, runs, and then has problems of its own finding other files 
outside that directory), that this chroot issue is indeed your problem.

No, as far as I know, hylafax has been this way for a long time, so I 
don't know how it could have worked before (or looking at it another 
way, that suggests that your problem is something else).

That's kind of a vague question; I can't say what it means.  It puts 
limitations on it, I guess.  Anyway, I don't think altering faxrcvd is 
the normal way to customize things.  I thought you were supposed to do 
that in FaxDispatch (faxrcvd will get overwritten on upgrades, 
FaxDispatch will not).  Not that that alleviates the limitation, but I 
think that is the recommended way.
