After server machine reboot, mongod fails to start with error code: 48.
Mitigation is to manualy run `sudo systemctl restart mongod` and it works.
I played aroung and at one point deleting mongodb-27017.sock file was needed
for mongodb to start, but after a reboot behavior went to the one I just describe.
I've tried combinations of mongod.service running and file pre booting status:

1. mongod.service - running mongodb-27017.sock -exist
2. mongod.service - running mongodb-27017.sock - does not exist
3. mongod.service - stoped mongodb-27017.sock -exist
4. mongod.service - stoped mongodb-27017.sock -does not exist

and problem persist.
What is a long term mitigation, ie, how to make mongod starts good after server reboot?
