This question was answered for a different distro, and was answered in a slightly different way. I understand why you'd want your answer to be definitive, but I think it's a little unfair to close this question as "duplicate." Maybe "similar" is more accurate.

HA! "mental." Yes, I was livid after spending hours HOURS on this problem. EC2's support hasn't helped yet either, telling me to try hostnamectl and nmcli, neither of which persisted the name on reboot. BUT! Your answer made me dig into how to make could-init override the hostname, and, by golly, IT WORKED! Hallelujah! THANK YOU. I'd accept your answer, but I think there are probably reasons to keep cloud-init installed, so I'm posting what to do.

comment Override DHCP hostname on RHEL5/CentOS/Amazon Linux
Unfortunately, this does not seem to work on CentOS7 (on AWS, with SELinux enabled, even with correct contexts). :-(

comment How to capture ack or syn packets by Tcpdump?
Your answer is technically correct, but the OP probably meant to include the word "only" in his question. ;-) Cheers!

comment How to capture ack or syn packets by Tcpdump?
That's a nice example. You can simplify your tcpdump capture filter even further by replacing "'tcp[tcpflags] & (tcp-syn) != 0' and 'tcp[tcpflags] & (tcp-ack) == 0'" with just 'tcp[tcpflags] == tcp-syn'. That will automatically exclude packets with ACK set. Cheers!
