Questions[defaults](server)

The XDG Base Directory Specification is a very interesting spec for user directories. It also provides good default values, except for XDG_RUNTIME_DIR.

Now I am writing a software that needs to create named pipes. It is a per-user client-server framework (there is a FIFO for the server and a FIFO per client).

If XDG_RUNTIME_DIR is not defined, I am currently using a per-user subdirectory in /tmp — but it does not ensure all the specified conditions (viz. the paragraph starting with "The lifetime of the directory MUST be bound to the user being logged in…")

Is /tmp/myserver-$USER good enough?

Edit

I saw elsewhere a few suggestions:

• . is quite unsatisfactory (at least because it is not an absolute path).
• I also saw /var/run/user/$USER — not bad, but that directory does not exist (at least on my box running a Debian testing)

This may be a bit of a noobish question, but I was taking a look at /etc/hosts on my new Xubuntu install and saw this:

127.0.0.1 localhost
127.0.1.1 myhostname

On most 'nixes I've used, the second line is omitted, and if I want to add my hostname to the hosts file, I'd just do this:

127.0.0.1 localhost myhostname

Is there a difference between these two files in any practical sense?

Can I deny "Internet Explorer" via GPO and use Google Chrome as a default and the only Browser?

I wonder as Internet Explorer is a part of an Windows operating system, if it's possible to deny it.

I would like to force users to use Google Chrome only as a browser.

Now that I have started the Software Update service on my Leopard Server, how do I change my client Macs to check for updates on it?

I would like to move the default location of my c:\Users\USERNAME to another drive. What is the easiest way to do this and how?

I know that I can move each of my "Special Folders" like Documents, Pictures, etc. but that does not include the AppData folder. Also, many programs and installers incorrectly put stuff in C:\Users\USERNAME\Documents etc. even after I moved Documents to another drive and I end up with duplicate folders.
