Regenerate from keyfile not symlink
Fixed regenerate method to regenerate the symlinks from actual key files and not the by-email symlink. The database and symlinks can now be restored from a backup by:
- Extracting the backed up key folders:
tar -xf 2022-12-27.tar.gz
- Moving the extracted key folders to
keys_external_dir/pub
- Running
hagridctl regenerate
