comment ZFS reads on FreeBSD incredibly slow
FWIW, our experience on FreeBSD 8 & 9 shows that ZFS snapshots have no notable impact on performance; unlike UFS and LVM snapshots which seem to suffer performance impacts after only a few snapshots. We've had 30+ snapshots on some very active filesystems. But that's just our experience.

comment freebsd-update from 8.3-RELEASE to 9.0-RELEASE: How to deal with dozens of diffs?
My systems do have that setting (I think it's a default). The trouble is, the files are slightly modified and FreeBSD forces a diff for those (The $ID$ tag is different between 8 -> 9, the root password is set, etc.). It's a known problem that FreeBSD never fixed. Now that we're on FreeBSD 9, this may not be an issue upgrading to 10 if we decide to stay with FreeBSD.

comment Database backup encryption
Can you elaborate about generating multiple keys? Would we just encrypt with multiple --recipient statements?

comment How to maintain site.pp with many nodes?
Would an ENC be a reasonable solution to this question? I would love to see someone comparing site.pp to ENCs.

comment How to maintain site.pp with many nodes?
@Felipe There is no simple alternative that I know of. Classifying nodes using files like site.pp or import 'nodes/*.pp has fallen out of favor in the Puppet community, particularly by PuppetLabs. I'm still not clear what the best alternative is, but it seems that the favored workarounds are Heira or use an ENC such as The Foreman or Puppet Enterprise. Discussion of those alternatives are fairly detailed and worth a whole discussion. I did try: ask.puppetlabs.com/question/10975/…

comment Difference between RH-Firewall-1-INPUT and INPUT
The RH-Firewall-1-INPUT chain was indeed removed with EL6. However, I cannot find any mention of this in the Release Notes. Does anyone have a link to the authoritative documentation stating the RH-Firewall-* should be replaced with INPUT? This is the source of much confusion for EL6 admins.

comment List of packages for RH 5.x
RH 5.3, 5.4, and 5.4 Beta are very old versions of RHEL 5. The latest available version of RHEL5, and the only version that should be used these days, is RHEL5.11. Anything older has missed out on security and stability updates and is at risk of being hacked. Consider a move to RHEL6 or RHEL7, which are the new versions of RHEL.

comment Changing network boot order (pxe) using ipmitool
> It is very,very rare there are multiple physical Ethernets on a server that support IPMI. I'm not sure what you mean by this. Every Intel and Supermicro server that I've had has two NICs on the back. NIC0 does the PXE by default.

comment Changing network boot order (pxe) using ipmitool
Using Supermicro X8 & X9 motherboards, you cannot specify the interface. You can only tell the system to PXEboot, and it will PXEboot in the order specified in the BIOS. You can reorder the PXEboot order in the BIOS, and change/disable which interfaces provide PXE, but that's all I've been able to do.
