Reinstalling ubuntu and fog

[Philippe]

Hi,

I need to reinstall on an ubuntu server and fog

/images is on its own hard drive.

Can I simply make a backup of the fog database and then

1. reinstall ubuntu and fog on the first hard drive
2. copy the database back.

or can I reuse the /images folder directly on a new install

I noticed on the forum that ubuntu 12.04 was giving problems to some people. What version to choose ?

Thanks in advance

Philippe
