I'd like to remaster Knoppix or Morphix on my Gentoo box but did not create an extra partition when I fdisk'ed my drive. Is there a way to resize my current partition without destroying any data on it?
Any help or pointers appreciated. I did google for this but being a newb I'd like to confer with someone about the best way to go about this. |

Remaster? To make a livecd or to work with them on the hd?
If the response is the firs you can make a loopback filesystem on an easy way.
| Code: |
dd if=/dev/zero of=/path/to/file bs=1024 count=700000
mkfs.reiserfs /path/to/file
mount -oloop /path/to/file /mnt/knoppix
|
Then you can access your loopback filesystem on /mnt/knoppix.
The example creates a 700mb filesystem, you can change these value if you want.[/code]
[EDIT]
Postdata: there are resizing tools, but i don't know anything about reiserfs, anyway, if it exists is, for sure, unsafe to use.

Thank you for the reply. I did not really want to resize and I figured there was a way to remaster and create a live cd without doing this.
I hope you don't mind some more newb questions relating to your post. I did some googling to find that a "loopback filesystem allows new virtual filesystems to be created to provide access to existing files using alternative pathnames. The most common use of lofs is by autofs to mount filesystems, exported by the local host, via /hosts. After the virtual filesystem is mounted, other filesystems can be mounted within it, covering, but not affecting, parts of the original filesystem. However, filesystems which are subsequently mounted onto the original underlying file system are visible to the virtual file system, except that recursive traversals are not allowed, i.e if / is mounted on /newroot, access to /newroot/newroot would not lead to another filesystems, rather it will appear as a normal directory, just as it was on the original underlying filesystem before the mount."
I think I understand what that means but do I have to recompile my kernel to be able to mount a loopback filesystem or can anyone do this regardless of what options were checked when a kernel was compiled? |

I want to make sure I understand what I substitute in your code to make this work on my system. tells dd to copy from a file right? Which file is /dev/zero ?
Do I substitute for
Why are you suggesting reiserfs above?
Thanks for helping a newb out. |

It's just a special character device file that contains the value of zero. You can use anyfile for this, since when you do mkfs part the file will be reformated, it's just the standard way to create a file, there are many other ways too.

Yes, but remember that is /home/soma1, you missed the first slash.

You can use your preferred fs, I like reiser but ext3 is also a good one. |
