hi, i want to rebuilt my debian (unstable) system on my laptop, using a crypted setup (just in case). i would like to use etch installer that supports the lvm and ciphered installation. i've only a doubt, i would like to keep the Other OS (for some application I need) but the lvm setup ask me about formatting all the first disk. Is there a way to keep the OtherOS and use the rest of the disk for a ciphered installation?
