Here I'll discuss Lumpy Linux, my custom mp3-playing distrib. Someday... :)

Here's a list of the software that I'm using right now:

• busybox - multi-call binary that provides init, and most of the basic utilities that an operating system needs in a real small binary. Small = more room for mp3's. It has a built-in shell now!
• perl - a really nice scripting language that has modules available for pretty much everything. I use it do most of the initial set-up of the player itself, and to do all the text processing that needs done (including driving the vacuum-fluorescent display).
• iproute2 - small ip configuration tools that replace stuff like ifconfig and route. If I can find source to ifconfig/route, I might use them instead... :)
• mpg123 - THE linux mp3 player. In the true unix way, it does one thing and does it well. There's just a command line, and with version "r", a "remote-control" API that makes all that perl scripting I did before it came out obselete. It also makes my player script way easier to maintain...

I was helped by:

• the Net3-howto
• the Bootdisk-howto.

I'm sure I asked luci members and the luci mailing list for some help with stuff along the way too. I'll prolly be using some of a guy's script to make the entries in /dev in my setup program, if I make one... :) I'll put in his name when I remember it (sorry).
