comment Link to a specific inode
This doesn't work for me. Given that '3' is a dangling symlink, not a "real" file descriptor, it always just creates an empty file.

comment Postfix — mail forwarding loop
Looks to me like it's the content filter feeding the message back into istelf, and the double-bounce or 'too many hops' message generating that warning.

comment Stop postfix logging “discarding EHLO keywords: 8BITMIME”
It doesn't hurt to leave it as is, and it's one less thing to remember/troubleshoot if you add features that need 7-bit clean content later, so I'd be inclined to leave it. And as Devdas said, include the pseudo-keyword "silent-discard" in your smtp_discard_ehlo_keywords if you want to suppress logging.

comment postfix - how do you redirect all emails to one user, eg *@example.com → user@example.com
Postfix doesn't make it difficult at all. Virtual aliases are the standard way to do catchalls in Postfix and they're very easy. That said, on anything but a toy mail server for your own personal domain, catchalls are a very bad idea.

comment Mailservers responding 220 ********************
Cisco PIX SMTP fixup makes SMTP less useful by effectively disabling ESMTP. Or it did when I last looked. It's almost never necessary or useful in front of a Real MTA.

comment Postfix performance
There shouldn't be any reason to try and reduce the amount of logging, as long as you have syslog logging asynchronously and (preferably) have the logs and spool on different spindles. Do make sure you're not doing any verbose logging for normal operation, though.

comment What tools should every sysadmin use that no one's heard of?
Not necessarily. It's no particular bash love, but more the good-enough-and-ubiquitous factor that keeps me on bash. Personally, I think of ksh as a good scripting shell but not a great interactive shell. I know you can technically do programmable completion in ksh, but it's icky compared to bash or zsh completion, and there's no ksh equivalent to the bash-completion project that I know of. (Oh, and you can set -o vi in bash too, you know).

comment Hidden Features of Solaris/OpenSolaris
pkill (and pgrep and the other p-utilities) are part of the core system package on (Open)Solaris. They're (at least pkill/pgrep/pmap) in procps on Linux.

comment Hidden Features of Solaris/OpenSolaris
I dunno, "export PAGER=less" works well enough for me. And you're better off with pkill than killall on Solaris. You're right about the sucky termcap/terminfo stuff tho (no terminfo for screen? GTFO!).

comment What solutions exist to allow the use of revision control for server configuration files?
Yes, but you should also revision-control your Puppet/CFengine configs. I'm also a fan of revision-controlling the output so that you can answer the question "what was the config on date x?" as well as "what should the config have been according to puppet?", and correlate inputs with outputs for troubleshooting the config management system.
