fedora 20 to 21

[Patrick Dupre]

Hello,

Trying to upgrade to fedora 21. I did:
mount /dev/sr0 /mnt/cdrom
fedup --device /mnt/cdrom --product=nonproduct

then 
'System Upgrade sda (fedup)

But it failed and reboot:
I just had time to see something like 
Failed to mount ....

Is it because it did not mount /dev/sr0 ?

This what is in the grub.cfg

menuentry 'System Upgrade sda (fedup)' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-3.3.4-5.fc17.x86_64-advanced-da1fb213-c138-4711-aba2-76a598506283' {
                load_video
                set gfxpayload=keep
                insmod gzio
                insmod part_msdos
                insmod ext2
                set root='hd0,msdos2'
                if [ x$feature_platform_search_hint = xy ]; then
                  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos2 --hint-efi=hd0,msdos2 --hint-baremetal=ahci0,msdos2 --hint='hd0,msdos2'  9089ac44-babc-47c3-9fb5-a51a95931a7d
                else
                  search --no-floppy --fs-uuid --set=root 9089ac44-babc-47c3-9fb5-a51a95931a7d
                fi
        echo 'Loading System Upgrade (fedup)'
                linux   /vmlinuz-fedup root=UUID=da1fb213-c138-4711-aba2-76a598506283 ro rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=latarcyrheb-sun16  KEYTABLE=uk rd.luks=0 LANG=en_US.UTF-8
                echo 'Loading initial ramdisk ...'
        initrd /initramfs-fedup.img
}


I do not see anything wrong.
