The [vm.max_map_count][1] paramater will be increased from the default `65530` value to `1048576`.

This change should help address performance, crash or start-up issues for a number of memory intensive applications, 

Performance improvement is unlikely but could allow something to run that otherwise would not.  The lkml comment [1] is worth a read and includes :     "To be clear, what you are doing here is akin to adding more memory to    your system when there is a memory leak. This is not the solution you    should be pushing. Ironically, this is using more memory and performing    worse than it should. At best, the limit increase is a workaround for    buggy programs." As Robin said, setting the max higher is probably benign - and only impacts a system running the problematic software (games). Nonetheless, it is very simple to change it to whatever value you want with your own prefs dropped into /etc/sysctl.d/xxx.conf gene  [1] https://lore.kernel.org/lkml/566168554.272637693.1710968734203.Jav aMail.root@zimbra54- e10.priv.proxad.net/T/#m1905a48f415bc6e8069a8fe53dec44bc311571f2 -- Gene
