Bug Description

uwsgi unable to start because value listen backlog option is bigger than net.core.somaxconn value

I tried to add sysctl -w for uwsgi.pp, but build of iso is failed because of read only filesystem:

"Read-only file system" setting key "net.core.somaxconn"

This revert does not fix the issue, we still have to address net.core.somaxconn somehow

I researched it a bit, and looks like that modifying /etc/sysctl.conf and then providing sysctl -p using docker entrypoints [1]
should work

Matt, are you working on the bug or we should reassign it back to fuel-library and get some free hands for it?
