/etc/sysctl.conf and /proc/sys/vm/mmap_min_addr

I’m messing around with Open Embedded
Main Page - Openembedded

The instructions tell me to append the following to /etc/sysctl.conf:

# OpenEmbedded
vm.mmap_min_addr = 0

or do (as superuser)

echo 0 >  /proc/sys/vm/mmap_min_addr

The default value seems to be 65536.

Simple question for the gurus - will this break anything in openSUSE when next I reboot the machine?

I understand there are security implications.

Thanks.

Only answering from a google but I would of thought not really but maybe, it can be undone. mmap_min_addr - Debian Wiki

I have to say my default is low like the debian one to(Diff distro though), in regards to saving on reboot. The echo no the sysctl will survive a reboot.

Hazarding a guess but I suspect 0 was the default for a while.
