[SOLVED] unable to create persistent overlay with fc-15 live-usb

schneidz · 10-29-2011, 12:11 PM

hi, i am trying to create a fc-15 live usb but the persistent overlay is not working. i tired with both the gui liveusb-creator and with this command:

Code:

sudo livecd-iso-to-disk --overlay-size-mb 6500 Downloads/Fedora-15-x86_64-Live-Desktop.iso /dev/sdc1

(i also tried with --overlay-size-mb = 2000) but everytime i boot the live-usb and type something like touch hello.txt then reboot, hello.txt is nowhere to be found.

i am using this usb drive:

Code:

Fedora 15 livecd's had a problem with "persistent overlay". Sometime after packages were updated and persistent overlay worked again but you have to create a new "spin" that will contain the updated packages. I used "livecd-creator" and a kickstart (.ks) from the "spin-kickstarts" directory. If you create a new spin it will have all the new packages that are available during your build.

thx, but i am not really following. do i start by downloading a different iso ?

thanks,

edit: i stumbled across this:
http://fedoraproject.org/wiki/Common...ounted_on_boot
so i am trying to figure out how to make sense of it.

I believe persistent overlay sizes are limited. FWIW, I've never gone above 1GB in any of my attempts. If you've got enough space for a 6GB persistent storage file, why not just do a full install to the flash drive?

i figured this out. i had to do:

Code:

sudo livecd-creator --config=/usr/share/spin-kickstarts/fedora-livecd-desktop.ks --fslabel=schneidz-fc-15 --cache=/var/cache/live

then ran sudo liveusb-creator using the newly created schneidz-fc-15.iso as input.

thanks,

for some reason i assumed i needed to do something like loop mount the original Fedora-15-x86_64-Live-Desktop.iso so i can merge the changes with it...
