Building Embedded Linux from Scratch

Cross-compiling not standardized; each package different

Best practices dictate that you script the cross-compile

Laziness dictates that you use someone else's scripts :-)

ptxdist is a collection of Makefiles, one per package,
so you don't have to reinvent the wheel
"make menuconfig" picks which programs to install
Supports about 80 packages so far (e.g. strace, nmap, oprofile, inetutils...)
