This is probably a very simple question but it has me perplexed. I just installed Red Hat Enterprise 5 on a 160G hard drive that I partitioned into two, 80G and 80G more or less. The Enterprise install worked nicely. I manually set the partitions for the install and wanted the extra 80G unused partition to be ext3. I hope to put FC7 or something else on that partition in the future to play with. When I mounted the partition I noticed it had a file called rhinstall-stage2.img which is around 80M in size. Can anyone tell me the purpose of this file? I'm wondering if maybe I should have just left that partition unformatted and let the next installer format it for me instead. All I wanted was for the Red Hat installer to format it and be done with it. I didn't want it to leave a fingerprint on that partition. I'm afraid of using any of that disk now in case somehow I'll have to delete that partition one day and start over.
