Usually you don't want to install RPM's, but only the files you really
need in your embedded root file system.

RPM comes at a pretty high cost in  terms  of  libraries  needed  and
databases it creates. This adds a lot of memory footprint for - well,
for  what  exactly?  On  the  target,  you usually don't even want to
install the full RPMs (which usually include stuff  like  man  pages,
info pages, documentation under /usr/share/doc, etc.).

So the first question you have to answer is: do you really, really
need package management on the target at all? Usually you dont.

And if you do, is it RPM?  Usually  it  isn;t.  Busybox  for  example
includes  dpkg  support,  which  is much leaner. If you really want a
packaged based target root file system, you can for example repackage
the needed files (omitting all the stuff not relevant for an embedded
system) using this.
