comment Should I exclude all 'dev/' or only 'dev/pts/' during full server tar backup?
Note that udev is Linux specific. On other unixoid systems with a static /dev, it is indeed advisable to include it in the backup, and only exclude /dev/pts, which is dynamically managed even there.

comment How do I edit the SSH “last login” message?
The "last login" message is user specific, while the motd is system-wide. I'm not sure how you want to recreate the message. Also, there are people who actually read this message, and want it to be as accurate as possible.

comment Why is ARIN (etc.) allocating such large blocks of IPv6 addresses?
Also, using stateless autoconfig and security extensions, you get a fairly spread out use of address space, so it is no longer economic to scan for machines on the Internet, which is a large attack vector for worms.

comment A domain I've never heard of resolves to my website
The error is transient. It means that the grace period for rebinding the socket (120 seconds IIRC) has not yet elapsed. For config changes, reload is usually sufficient.

Your VirtualHost should have a ServerName -- that is the warning.

comment SNMP tick counter wrap around logic
You can detect a wrap easily (counter decreases) and correct by adding MAX+1 -- however if the counter was reset because the agent was reset, this would look like a wrap, so you don't correct if the sysUptime.0 also decreased.

comment Do wifi packets go directly node to node?
Both modes are allowed, unless the AP explicitly forbade. The stations decide which next-hop address to use.

comment Process for configuring network settings on a headless rack mount device
If it should be deployed in a datacenter, please make it configurable by SNMP and add either VLAN or a separate configuration interface to allow for separation of user and management data. Failing that, serial console on RJ45 plug and an option to turn off management from the network.

comment NAS device claims drive in a RAID is degraded but S.M.A.R.T. says it is fine
Also, you need to have "offline data collection" enabled in the drive, otherwise a lot of data will be missing.

comment Best way to execute a command after Linux system halt
Perhaps I'm missing the blindingly obvious, but shouldn't IPMI access be happening on a separate LAN that is accessed from the management console and ideally inaccessible to the host?

comment Why does deleting a big file take longer?
One file will always just use one inode. It does use multiple data blocks.

comment What's so special about leased lines (T1, DS3, etc)
Anecdata to illustrate the point: I have a "business" SLA on my DSL line at home. Replacing a dead DSL modem took four hours (they store replacement modems at the local UPS hub for that reason).

comment Is it necessary to have RAID in a virtual machine?
The problem with hardware RAID is that only few solutions respect I/O priorities, which can lead to suboptimal scheduling.
