[olpc-software] Package manager stuff

[Mike Hearn]

Oh, another potential advantage, better power consumption.

RPM and other package managers are very resource intensive. On my
computer they use lots of memory, and trigger lots of disk activity as
they swap and move files around, update databases, regenerate caches and
so on.

Done right, merging in an application should be very lightweight: no
copying of files, no updating of databases, no memory overhead. Just
namespace manipulation.
