We hope the LMDE team (hallowed be thy names !-) will soon rectify this discontinuity. Meanwhile, LMDE users have a few workarounds (please let me know if more can be added) for installing LMDE with LVM2 or LUKS (and that's a Boolean "or"). In historical order (IIUC):
- See hashstat's manual process from this LMDE1 tutorial. Perhaps someone could check to see how it works for LMDE2, and revise as necessary? (Note initial LMDE2 releases for Cinnamon and MATE.) Again, please lemme know how that works, and I'll update this tutorial accordingly.
- Not long after hashstat published the above, Pepas began to automate the procedure. Because Pepa's code was not in a repository (making distribution of and collaboration on code difficult), Tom Roche put his then-current code into this project and began updating there. (Your `git` pull requests are welcome!)
- Pepas now has a git repo.
Again, we hope that the LMDE installer will soon support encrypted or resizing, making our workarounds redundant. That being said, ISTM that, the more we as a community can do to solve this problem, the more likely it becomes that the LMDE team will takeover maintenance.
