Keith Turner commented on ACCUMULO-1385:
----------------------------------------

bq. An example of an RPM that does add its own modular config to /etc/sysctl.d

I did not even notice "/etc/sysctl.d/accumulo" in the summary.  Putting it in 
/etc/sysctl.d resolves my concerns.

Following this line of thought, should we up nproc and nofile in 
/etc/security/limits.d?   It seems like adjustments to open file limits would 
need to apply to HDFS users more than the accumulo user, so that may be tricky.
                
> RPM/DEB should set vm.swappiness in /etc/sysctl.d/accumulo
