Red Hat Bugzilla – Bug 362141
I urgently need help in Fedora LiveCD
Last modified: 2007-11-30 17:12:20 EST
Sorry to ask directly in bugzilla, but I asked some questions
to the Fedora Project Brazil group, with no succesfull answer.
My name is Thiago Santana and I doing a derivative of
Fedora LiveCD for a Point of Sale application.
I need to understand a little bit of the Ramdrive
conceptual framework used in 'Fedora 7 LiveCD'.
There is a file system mounted on the root directory
("/"). How the system is it able to distinguish the
programs previously recorded on the CD image from files
and programs created by me?
If I understand correctly, some files are stored in RAM,
but I didn't get how the file system manages the
available storage space. I want to know how to calculate
the RAM space I need for my files.
Furthermore, it appears to be that when I open some file
from the image for editing, the full contents of the
file is copied to RAM. Is that the case? If it is so,
what happens if I open a great number of files?
I will be waiting for your response.
Thank advance your information.
My best regards,
