It’s a kernel restriction.
I think the main reason for these arbitrary limits is that in C it’s
easier to deal with fixed-size arrays than with dynamically-allocated
arrays. :-)
(A valid argument to limiting the length of file names is that it could
make it easy to DoS a system. But then, that limit could very well be
configurable at run time, pretty much like rlimits, if it were the only
reason…)
