Yes.

Short answer: Decompress the initrd, modify the filesystem, compress it again. Long answer: http://www.thegeekstuff.com/2009/07/...te-initrd-img/

Depends on what you mean with normally. The added files/folders will be accessible to programs/scripts that are running in the initrd. Once the init-scripts switch the root to the /-filesystem you will not be able to access them anymore.
