comment Can FPM make one RPM package that acts differently if systemd is being used?
I was hoping RPM defined a better place than putting them in /tmp. If I knew someone was going to write to /tmp as root, I'd put a symlink there to /etc/passwd so that when they wrote the file it would smash their password file. I mean... I wouldn't do that... but someone mean person might.

Where should the scripts be delivered to before they are copied to their proper destination?

comment Faster rsync of huge directory which was not changed
(sorry, I didn't see the update). Hmm... on 1.5M link you When I do a similar benchmark, if "ls -lLR" takes 1 second, rsync takes about 1.3 seconds. A 30% overhead for the additional processing that rsync is doing seems reasonable. What is the ratio for you? If you do a "tcpdump", do you see network traffic the entire time or a pause? If there is a pause, then the disks are your limit. No pauses, it is the network.

How slow? If you use "scp" to copy a 100M file, how long does it take? Also, what is the output of "time ssh remotehost 'cd /dest && ls -lLR' >/tmp/list"?

2k files per directory is a lot better. thank you for the update. You hadn't mentioned that the network was slow. Is it low bandwidth, high latency, or both? rsync usually performs well on high latency links (it was developed by someone working on his PhD from Australia while dealing with computers in the U.S.). Try doing that "ls -lLR" over ssh and time how long it takes to transmit the result. "time ssh remotehost 'cd /dest && ls -lLR' >/tmp/list". Make sure the /tmp/list gets created on the local host.

comment How do I use haproxy to load balance 2 postfix servers?
inet_interfaces is wrong. Only listening to local host means it won't receive email from the outside. I'm on my phone right now. Look at main.cf examples to see how to set it to listen to all interfaces.
