Jordan is speaking to hard limits.  The login.conf speaks to soft
limits, and is still limited to what it can set by the hard limits.

The hard limits are the result of static allocations, general at
initialization time before the kernel is really running, like
globally declared arrays.

AIX was probably right when it made all this stuff dynamic.  Then you
could at least sysctl the "hard limit" after the machine was up.
