yes, that I did forget to do. My apologies, as I was running late cause I had to take my kids to an event. I will get it first thing in the morning. Thanks.

A little late, but here is 'df':

[root@retail disks]# df -h mnt/
Filesystem Size Used Avail Use% Mounted on
/dev/loop0 3.0G 1.9G 988M 66% /home/clients/ubuntu/disks/mnt
[root@retail disks]#

And with the disk unmounted what does this show:

du -sk /home/clients/ubuntu/*

Its almost like it did not create the 3GB root.disk by looking at the disks folder being 5GB. I am almost positive i did the cp -a to move it from mnt old to mnt new...

There should be nothing under /home/clients/ubuntu/disks/mnt if you unmounted it. In fact that directory should not even exist when you create your zip if you followed my instructions. Also, what all is under /home/clients/ubuntu/disks? Looks like there is a lot more than should be there. Copy/paste the output of this:

# ls -lR /home/clients/ubuntu

the mnt folder was there and it was mounted so I umounted it. I must of left it during the second time I did it.

Here is the output:

That looks about right once you unmount the root.disk. After creating a new root.disk and copying the files over and unmounting it what does it zip down to by itself? I guess it might just be easier to just look at a listing of your zip file. Can you copy/paste the output of your zip file?

Code: Select all

unzip -v ubuntu.zip

That should show a list of the files in the zip file and their sizes before and after compressing.

You should go in your profile and enable BBCODE so when you use the "CODE" tags they actually work. You can also uncheck "Disable BBCode" when posting your message.

Regarding what I see in your file I see three things. First off get rid of that ".fuse_hidden*" file which will reduce the image size by over 700MB right off the bat. I forgot that I actually had that one too and had removed it early on (sorry!!).

Second one is your swap isn't getting compressed at all where mine gets compressed almost completely (you would gain over 200MB there). I think Fedora might initialize the swap when it exits which would explain it. You could create a new swap file before compressing:

Code: Select all

rm swap.disk
dd if=/dev/zero of=swap.disk bs=1M count=256
mkswap swap.disk

Third, as far as the root.disk file I would think that should compress down a bit more if you created a new file system and copied your files over from the old file system.

I'll get rid of Fedora off my VM and install Ubuntu again and see if there is anything else that would need to be done after creating a new swap file (possibly need a modification to the /etc/fstab).

byrdman · Post by **byrdman** » Fri Jul 24, 2009 8:30 am

Ok, I enabled the BBcode, so hopefully I look normal

When doing your instructions, I now got down to 800MB. This was creating a new swap disk and it did deflate 100%.
I did it again but this time creating a new root disk and copying the old root disk over, and ziped it up, I got down to 720MB.
So if I get in and remove more packages, will is shrink some more? I would like to be under 700 so I can place on a CD and ship to the sites

Void Main · Post by **Void Main** » Fri Jul 24, 2009 9:25 am

Yes, after you remove the packages you will have to recreate a new file system and copy over the remaining data to the new file system in order for the compression to work. Also, you should only need one kernel and one initrd (whichever one you are booting in your menu.lst). The others can be removed. That should gain you 10-15MB. You don't need the "uninstall-wubi.exe". On the file system itself check the /tmp and /var/tmp. Make sure the cache directories are clean etc (Firefox, apt-get, etc).

byrdman · Post by **byrdman** » Thu Jul 30, 2009 7:35 am

Following up: I have three systems up and running with the linux player, all built with different methods. One is a PC, built from scratch, one is ubuntu, loaded remotely with the wubi image copied to the windows directory and after modifying boot.ini, it booted exactly as planned. The third is fedora loaded onto an 'appliance' type pc, small enough where it could be mounted behind monitors if need be, but also really cheap, as it has the dual-core ATOM proc so these machines are about $325 each - $449 with a M$ os on them

After lettting them run for a week, it seems that the fedora image just runs better. It is easier for me to modify stuff and I just feel all around more comfortable with the fedora install.
So now the question is, do you think the fedora image could work in the wubi installer? I remember you said it kind of worked but that there were times it locked up?

Void Main · Post by **Void Main** » Thu Jul 30, 2009 8:28 am

Sure I think it "could" work, and if fact I have it working. The only problem I had with it was a problem with a shutdown/restart sometimes hanging because it wasn't able to unmount a file system because it was in use. That should be something that can be easily figured out though. I just didn't put any time into resolving that since you though you would just go with the Ubuntu install. I wish I had a higher speed connection (upload wise) so you could just download the image I have created. I could probably work out the shutdown/reboot issue and then dump it to CD and hand it off at a lunch meeting.

Or you could build the image yourself (like you have) and I could give you the steps I did to make it work. In fact I might have already done that earlier in this thread. It's basically nothing more than modifying/using the Ubuntu initrd image with the Fedora kernel (replace the Ubuntu kernel modules with the Fedora kernel modules in the initrd), and making a couple of simple changes to the /etc/fstab and menu.lst files. That would get you up and booted to where I am. I think one of the rc or service scripts will have to be modified to fix the reboot hang issue.

byrdman · Post by **byrdman** » Thu Jul 30, 2009 8:52 am

I will look through the thread and see if I can piece it together. I have a perfect fedora image that I think I would need to boot to a USB live OS to get the 'running OS' zipped up, correct?
If it is not too much trouble, a list would help, but don't lose sleep over it.
