What's the Dealio with initrd, etcfstab, initrd.img inittab, vmlinuz, grub and parbreastions 523

Oh...whoops; here's my etc-fstab

#etc-fstab: static file system information. # proc proc proc defaults 0 0dev-hda1 mnt-hda1 vfat noauto,user,umask=000 0 0dev-hda5 mnt-hda5 vfat noauto,user,umask=000 0 0dev-hda6 mnt-hda6 vfat noauto,user,umask=000 0 0dev-hda7 ext3 defaults,errors=remount-ro 0 1dev-hda9 home ext3 defaults 0 2dev-hda10 usr ext3 defaults 0 2dev-hda11 var ext3 defaults 0 2dev-hda8 none swap sw 0 0dev-hdd media-cdrom0 iso9660 ro,user,noauto 0 0dev-hdc media-cdrom1 iso9660 ro,user,noauto 0 0dev-fd0 media-floppy0 auto rw,user,noauto 0 0

I'm not sure if this is of any relevance, but when I installed Debian, I said NO to setting up any Mail Servers or Clients (just for now) - but more importantly, I DID set up a 'fake' domain (and name) - it was just a matter of making a change to the standard 'localhost' that's filled in for you, and then creating a domain name (blahblah.comcrap)...I have yet to see ANY of that domain-name info yet ANYWHERE on my box. Just thought it might be affecting my User permissions and such (I've gotten pretty good with K Control Center). This PC is a stand alone, wired Ethernet on Cable, with Router (no others networked to it - yet).
