Hi Conrad,

This patch makes me think about another related bug #184340 :
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=184340
It is about PATH_MAX which in some cases can be too small.

Not sure if it's the case / and how to do it,
but perhaps it is time to raise some other limits /
think about a global solution regarding these length limits ?

Many thanks !

Ben
