I have an oddball little tip this time, something that will be either a godsend or something you can conveniently forget. If you’re an Arch user and you find yourself needing to pass parameters to a module, you can do that from within the rc.conf file, instead of relying on /etc/modprobe.d/modules.conf.
For example, forcing an 800×600, 16bpp framebuffer resolution at 60Mhz vertical sync rate with the tridentfb module will require a command like this.
modprobe tridentfb mode=800x600-16@60
Ordinarily I would stuff something like that in /etc/modprobe.d/modules.conf, but I realized the other day that this line from rc.conf will do the same thing.
Encapsulating it in quotes allows Arch to handle the entire segment — module and parameters — without a hiccup. You can add other modules as you normally would or blacklist them with the exclamation mark prefix too, and they’ll work just fine.
Like I said, this is something slightly esoteric and might never be of use to you. (It might also be that this is common knowledge and that I’m repeating something everybody already knows. It wouldn’t be the first time. … )
On the other hand, if you can pass parameters to a module like this, it means you can rely on rc.conf instead of farming out to other configuration files. And of course, one of the beauties of Arch is the fact that 90 percent of the configuration takes place in that one file. Might as well keep it there.
