comment Why is the firewall disabled by default?
(Agressive pedant warning) I'd recommend users not allow random incoming UDP/53 packets on the basis of spoofable source address. They've been used in real-world attacks (DNS poison, DoS by amplified traffic). You would need to do this why?

comment How can I replace upstart with systemd?
Or just raring? On 13.10 systemd-services doesn't include /lib/systemd/systemd, and there isn't another package that does.

update link (fix fragment). Hopefully the instructions still work in this case... put the instructions inline, people!

comment Install Ubuntu next to Windows 8 (UEFI dual boot)
Upvote for warning about "not reckognize the windows partition". Same here on 13.04 - but you can keep windows by selecting the "something else" option, i.e. manual partitioning, and shrinking the windows partition. Subject to the safety issues around Windows 8 hibernation-by-default! For safety I'm guessing you need to "restart" out of windows first, instead of "shutdown". I forgot, so I mounted the windows partition and removed hiberfil.sys before booting back to windows - I don't know what would have happened otherwise but the worst case is pretty damn bad.).

comment fstab. allow 2 users mount NTFS with passwd. Deny other users. possible?
This should be possible using polkit (nee PolicyKit). Prompting for password should be possible too. udisks.freedesktop.org/docs/latest/udisks-polkit-actions.html. There are several different actions you can configure; I assume you'd want the fstab-related one. I would try using one of the UUID arguments to limit it to the specific filesystem.

Show verbose output, which demystifies it a bit... if you know what '/.' means

comment How to copy into with cp if destination folder already exists?
People use it that way, but it was invented for network transfer. If you're copying gigabytes of files locally, it's a few times slower it could be. Some measurements here: lwn.net/Articles/400489

comment How to prevent so many instances of apt-check running?
Nagios/Icinga seems to avoid the pitfall. At least, it had some 10s timeout and warned if it was exceeded. (Though I can't find how to configure the timeout - I'd prefer longer). Byobu on Debian is what caused the problem for me; on Ubuntu it's supposed to be fixed.

comment How well are SSDs supported?
SATA TRIM can't be queued. It can also take some time to process, and/or leave the drive "busy" (slower) for a time afterwards. Guess what, it turns out invoking it after every single delete is not automatically a good idea. Just going from the specification, If you want an OS to "support" such a unique command

Explain _why_ fsck creates an empty lost+found (and therefore why you might not want to remove it)
