Subject: Don't let '--write-signature' overwrite unique signatures.
|
|
References: bnc#
|
|
|
|
Using '--write-signature' on an MBR-partitioned disk always overwrites
|
|
the previous signature, even if it was already unique.
|
|
While not using GPT is against the spec, it still works most of the time.
|
|
The issue is, that excessively writing new entries to NVRAM (and incidentally
|
|
breaking all old references to the partition in question) was found to
|
|
bring trouble to certain systems.
