This is a tracking bug for Change: Switch cryptsetup default metadata format to LUKS2
For more details, see: https://fedoraproject.org/wiki/Changes/SwitchCryptsetupDefaultToLUKS2
The change switches Fedora system default metadata format for full disk encryption from LUKS1 to LUKS2. It mostly involves cryptsetup package and Anaconda installer so that both creates new LUKS2 containers by default.
For cryptsetup, I've switched default format with following build: cryptsetup-2.0.6-2.fc30.
Anaconda switched the default format in anaconda-30.19-1.fc30.
Encrypting a LVM Volume group (so LVM on top of LUKS) in the Custom partitioning screen creates a LUKS1 partition, with no way to change it.
Automatic partitioning with encryption (also LVM on top of LUKS) creates a LUKS2 partition. Any way to have a LUKS2 partition below LVM with Custom partitioning?
it should be possible to change the version of LUKS in the Custom partitioning screen.
Please, report a bug against anaconda and provide steps to reproduce.
