Subject: [PATCH 2/4] cryptodisk: Fallback to passphrase
|
||
|
|
|
||
|
|
If a protector is specified, but it fails to unlock the disk, fall back
|
||
|
|
to asking for the passphrase. However, an error was set indicating that
|
||
|
|
the protector(s) failed. Later code (e.g., LUKS code) fails as
|
||
|
|
`grub_errno` is now set. Print the existing errors out first, before
|
||
|
|
proceeding with the passphrase.
