Installing dual boot on existing encrypted LVM

[coviran]

Hello,

I have a working system with a lvm partition containing various encrypted volumes:



fred:~# lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
home fred -wi-ao 124.80G
root fred -wi-a- 9.31G
root_testing fred -wi-ao 9.31G
swap fred -wi-ao 4.66G


All the volumes are named intuitively with an existing Debian testing installation on "root_testing" using "home" and "swap".

I would like to install Ubuntu on "root", preserving the other volumes, so that I have a fully encrypted dual boot system sharing the same home directory. Before trying that I would like to ask you for some advice:

- I read lvm is only available with the "Alternate Install CD". Is this still true, even when lvm is already set up?

- Are there dangerous steps of the installation where I do have to be very careful not to overwrite / format / erase ... my existing partitioning / lvm setup?

- Has anyone done this before, are there guides, hints, anything?


kind regards,
covi

I don't think this is exactly what you are doing but it may give some strong pointers as to how to proceed.
Good luck.
