Subject: [PATCH] disks: fix reuse of statically keyed LUKS volume
|
||
|
|
|
||
|
|
We need to persist a volume's keyfile to the real root even if we take
|
||
|
|
the early `continue` when reusing the volume. Rather than copying code,
|
||
|
|
enable persistence up front and then disable it afterward if we decide
|
||
|
|
not to persist the key.
|
||
|
|
|
||
|
|
Fixes error:
|
||
|
|
|
||
|
|
CRITICAL : Ignition failed: creating crypttab entries: missing persisted keyfile for [...]
|
||
|
|
|
||
|
|
Fixes: https://github.com/coreos/ignition/issues/1305
|
||
|
|
Fixes: 65e9c1611128 ("stages/disks: use State to persist keyfiles for files stage")
