As everybody knows ,Fedora 12 is out, If maybe you still running the old version like Fedora 11 or 10 and you need to upgrade to fedora12, then you have to know that upgarding to this release is only possible from Fedora 11, if you are using an older version, you will need first to upgrade to Fedora11 before to go to 12.
Before to start the upgrade, remember that is important to take a look on the upgrade page of fedora before to upgrade , because you can have more advises about upgrade procedure.
Important : Make a complete backup of any important data before performing an upgrade. Important data may include the contents of your entire /home directory as well as content from services such as an Apache, FTP, or SQL server, or a source code management system. Although upgrades are not destructive, if you perform one improperly there is a small possibility of data loss.

Still, no joy.
Trying to upgrade my vanilla F11 installation, I get the same error using any of the three methods.
It says it needs more space (13M) on /mnt/sysimage/boot
and it exits.
This is extremely disappointing. I guess /mnt/sysimage/boot is a ramdrive and if it cannot squeze everything it needs in the space it allocates what is there for me to do.
The system has 768MB of RAM if that matters (it shouldn't).
Thanks/.


You could add the upgrade procedure using the Fedora 12 DVD.
Thanks.
