CentOS 5.5 installation on disk image

  • 772

Today, in order to install CentOS 5.5 I'm using kickstart script.

I would like to install CentOS on different way:

  1. Create disk image (using dd command)
  2. Create filesystem on this disk image using mkfs.ext3
  3. Install CentOS on this filesystem
  4. Make this disk image bootable (using grub-install)
  5. Copy the disk image to the physical hard disk (using dd command)

I know to do all these items except 3. Is it possible to do it? If yes, how can I install CentOS on the disk image?

linux centos installation filesystems dd

  1. CentOS uses several mounted filesystems. Typically /, /usr, /var, /home are each on different partitions. This complicates the idea of doing a normal CentOS install.

    If you are after disk images, then your best bet is to install CentOS on a 'test' computer manually. Then use a disk-imaging bootdisk to create images of each of the partitions in /etc/fstab.

    Perhaps if you shared more information on what your are trying to accomplish, or why you think you need to install CentOS differently than it's designers had intended; then I could provide a better answer.
