LiveCD maybe the fastest way for end users to experience new systems, almost every linux distribution supplys such a thing. But LiveCD got its limitations: you need a CD/DVD drive populated in your computer, you run into extreamly slow perforance issues, you can not install any software, you can not save anything you changed to the new system, ……, etc. When I tried "Fedora 12 snap3" LiveCD in my laptop, I even found out that the mouse cursor could not locate things correctly, there was more than one inch offset to the right position!
This tutorial describes how to install Fedora 12 LiveCD to harddisk. I don't issue any guarantee that this will work for you.
1 Preliminary note
I use Fedora 12 snapshot 3 LiveCD, you can find the download address in the last part of this article. The image name is F12-Snap3-x86_64-Live.iso.
2 Have a look at the layout of the image
[root@beta-song mnt]# mkdir livecd squashfs ext3fs
[root@beta-song mnt]# mount -o loop F12-Snap3-x86_64-Live.iso livecd
[root@beta-song mnt]# ls livecd
EFI GPL isolinux LiveOS README
[root@beta-song mnt]# ls livecd/LiveOS/ -l
total 649461
-r-xr-xr-x 1 root root 21364 Sep 18 07:12 livecd-iso-to-disk
-r-xr-xr-x 1 root root 8192 Sep 18 07:13 osmin.img
-r-xr-xr-x 1 root root 665018368 Sep 18 07:15 squashfs.img
[root@beta-song mnt]# mount -o loop livecd/LiveOS/squashfs.img squashfs
[root@beta-song mnt]# ls squashfs
ext3fs.img
[root@beta-song mnt]# mount -o loop squashfs/ext3fs.img ext3fs
Now see what we got, there they are:
[root@beta-song mnt]# ls ext3fs/
bin boot dev etc home lib lib64 lost+found media mnt opt proc root sbin selinux srv sys tmp usr var
3 Install the system to harddisk
Prepare a new Ext3/Ext4 partition, let's say /dev/sda2.
[root@beta-song mnt]# mkfs.ext4 /dev/sda2
Copy all the stuff under directory ext3fs/ to the partition.
[root@beta-song mnt]# mkdir sda2
[root@beta-song mnt]# mount /dev/sda2 sda2
[root@beta-song mnt]# cp -dpR ext3fs/* sda2/
Modify the first line of /etc/fstab to make it right for our case:
[root@localhost mnt]# cat sda2/etc/fstab
/dev/root / ext4 defaults,noatime 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
Change "/dev/root" to "/dev/sda2" as our case, then add new grub entry for this system. we are done!
