I have Ubuntu 10.04 installed with encrypted home directory. /home is on a aseparate partition. Can I just boot from 10.10 cd, reformat '/' and install as usual? I think it should work if I use the same password? Will it? Is there anything else to keep in mind?

I have previously done this on Ubuntu and Mandriva.

This will work and you will be able to mount your existing /home partition even if it is encrypted as long as you know the passphrase.

Thing to keep in mind is to set up the mount points correctly and don't accidentally format your /home partition.

Will the installer ask for the passphrase or will it be asked on first login? Or do ineed to enter it manually somewhere? –  papukaija Jan 28 '11 at 16:18
    
Actually you don't need to know the passphrase, just the password that will be asked when you first login after the installation. –  desgua Sep 17 '11 at 0:15

You should take a note of your mount passphrase. This is covered on the page

It will work as long as you use the same username and password.

Actually you won't need the passphrase, just the password that will be asked when you first login after the installation.
