Comment 2 for bug 217138

I would like to see this, too. It would really help if cryptsetup and lvm2 package is already installed in the live image and related modules (dm-mod, dm-crypt, aes) would be already loaded.

As an exmaple case you would need it after your harddisk got corrupted and you installed with alternate cd and lvm encrypted volumes. To access your data and fix things you now need a network connection, install cryptsetup, lvm2 and load the modules (intrepid).
