There are several options:

* Add more RAM (which is obviously the  simplest  solution  from  the
  perspective of a software developer)

* Reduce the size of the ramdisk - it defualts to  4  MB,  but  AFAIR
  only about 2.5 MB are used

* Don't use a ramdisk at all, but instead put  your  root  filesystem
  into a cramfs or JFFS2 filesystem

* Optimize the kernel  configuration  by  throwing  out  drivers  and
  filesystems  you  don't  need; the default configurations is _very_
  generic (with NFS, ext2, cramfs, JFFS, JFFS2, msdos filesystems).

Hope it helps,

If this is a service economy, why is the service so bad?
