Thank you oobetimer for the most interesting HowTo post.
I've been using Mint LiveMedia for nearly 4 years and have complained a lot about the various nuisances running these systems. I have been thinking about remastering my own version for quite awhile, but am just getting around to it. I was shown the link to this thread and decided to give it a try. However, the ISO file I created and burned via USB Image Writer was not successful in generating a bootable USB drive. I have never had any significant trouble burning bootable LiveMedia for any of the downloaded Linux Mint distro ISOs.
Here is my system: Linux Mint 15 32-bit Mate LiveDVD on a locked SD card, with an external USB hard drive. I already had a copy of the exact ISO file you used for your demo on a data DVD.
Here is what happened: I understood most of the commands and proceeded without difficulty up to step 7:
7. Extract squashfs and move extracted to folder edit
sudo unsquashfs mnt/casper/filesystem.squashfs
>There was one comment during the unsquash: create_inode: socket squashfs-root/run/samba/unexpected ignored
Is this a problem?
I just wanted to try remastering a system, so I did not change any packages and skipped step 13.
I proceeded through the steps up to step 17
17. Make ISO
sudo mksquashfs edit extract-cd/casper/filesystem.squashfs
sudo printf $(sudo du -sx --block-size=1 edit | cut -f1) > extract-cd/casper/filesystem.size
>Got this message: bash: extract-cd/casper/filesystem.size: Permission denied ??? Is this a problem?
I just kept going and I did get an ISO file which I burned onto a USB thumb drive with USB Image Writer. Nice try, but when I try to boot it I just get a BIOS message:
Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
I would sincerely appreciate any and all comments, suggestions, and assistance in getting this to run.
Blessings in abundance, all the best, & ENJOY!
