Comment 12 for bug 1756840

I currently have several installs with encrypted homes. Today I was going to upgrade the first of them, in this case, from 17.10 to 18.04. Having one last scan of the release notes before upgrading, I spotted this issue (https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes#Other_base_system_changes_since_16.04_LTS, 4th bullet). The text there makes it sound like you can no-longer setup encrypted homes using the installer... but that existing encrypted homes should continue to work fine. To be sure, I clicked through to this bug report, and read the summary. Again, there is nothing there to give any indication that existing encrypted home directory setups will be affected adversely. The following surely applies to setting up new encrypted home directories, not to upgrading setups with encrypted homes to new Ubuntu versions? "Support for installing using ecryptfs encrypted /home has been disabled in the installers." But then I read through to comment 11, and now I'm not sure.

I need certainty before I upgrade, so some clarification would be greatly appreciated.

If I upgrade a pre-18.04 system that has an existing encrypted home directory setup, will it continue to just work after upgrading, or will it be broken in some way? If the latter, what exactly needs to be done to fix this? (Also, if the latter, why on earth would you take a deliberate decision to break the systems of people using an advertised feature for years without providing a suitable upgrade path and without even properly advertising it?)

Thank you.
