The soft limit has some merit, since some (old) programs still cannot
handle file descriptors about 1024. On the other hand, I see no reason to
keep the hard limit that low: if a program changes the limit, it probably
knows what it's doing, and a few thousand file descriptors should not be
prohibitive on a modern system, even an SBC.
Please consider increasing the default nfile hard limit. 16384 should be
a fine value for most setups, but you might consider going the full way up
to 65535.
