Re: Behavioral differences between versions.
Paul, Thanks for the information. I'll see what I can find in the NEWS and OLDNEWS. Hopefully that will give me what I'm looking for on most of the questions. Am I correct in my assumption that Redhat does not tweak the rsync it ships with its distribution?

Re: Behavioral differences between versions.
Matt, Thanks for the information. I've found Red Hat often slow and difficult to get an answer from. I'll check the differences between the rhel4 and rhel5 versions in the SRPMs. I'll also check the bug tracking. I have found one issue I thought was probably just a change in behavior that was reported as a bug.

Behavioral differences between versions.
Greetings, We are upgrading systems in our lab from rhel4 to rhel5. We've noticed a number of differences in behavior while using the same arguments on the same data set. We get different sent and received counts. We also had one case with some data corruption that was only fixed after telling rsync to checksum everything. I was hoping someone in the list can point me to some better information. There are 2 points of interest. 1. When using the -z option, does rsync actually use /usr/bin/compress or does it use gzip? The man pages say it compresses data but doesn't specify what it compresses with. 2. I was looking for detailed documentation on behavioral changes of arguments between rsync versions. If I can't find anything in the documentation I'll post more details about specific behaviors later.
