Comment 116 for bug 84591

When building a custom LiveCD adding `export PERSISTENT="Yes"` in `/etc/casper.conf` works.

Bootable USB-sticks should be fixed by editing the `/boot/grub/grub.conf` that you will find on your USB-stick. Replace the following part

```
menuentry "Try Ubuntu without installing" {
 set gfxpayload=keep
 linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash --
 initrd /casper/initrd.lz
}
```
with
```
menuentry "Try Ubuntu without installing" {
 set gfxpayload=keep
 linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --
 initrd /casper/initrd.lz
}
```
(the new thing here is the `persistent` flag).
