How can I reduce number of ttys in /dev -- or is it worth the trouble?

I'm running Arch Linux at the moment, but I've seen this same thing in every other distro. If I list the device files in /dev, I see 63 ttys and vc's listed. I know that vc's are virtual consoles, I think they're the same as ttys, but I don't know.

My questions are:

1) Can I set a lower number of ttys to have available? Even if it involves recompiling the kernel itself, just tell me where the setting is.
2) If so, how?
3) Does having so many use more memory?

EDIT: I'm not asking the same question as here. That tells the kernel to not start getty (or similar programs) to manage a tty; I'm looking to not have the tty exist at all.

I found this guide for crunchbang.

I haven't had a chance to look into whether this works with Arch or not.

Unfortunately, there is no console-setup file or events.d in Arch, so far as I can determine, so no luck.

Searching the Arch Wiki for console-setup didn't offer anything useful, either, at least in the department I'm looking for.

Ha, it seems like it's much easier than I would have supposed.

You should just be able to comment out the virtual consoles you don't want in /etc/inittab

Why bother? They don't take up any space to speak of. FWIW, a tty is needed for each xterm/console/virtual terminal you start up. Basically, in your case, these are just place holders.
