Re: [dm-devel] What is the deal with the partition separator?



Oops, didn't see this until today because this darn mailing list mangles the reply-to header. *shakes fist*

Currently all of the tools check by trying to open the expected device name. If they have different ideas of what that is, the check fails to find the existing instance. It is looking to me like the way to fix this is to patch dmraid and libparted so that they conform with the kpartx and "linux since the dawn of time" method of only adding the 'p' if the previous character is a digit.

Partitions should be created only once, in one place.

If a second instance of anything tries to create them too, it should,
by default, detect that they are already there and not proceed.

You should not be able to run kpartx twice on the same underlying
disk with different delimiters without some sort of 'force' option.

(Check by querying /sys/.../holders ?)
