UBIFS: mount based on UUID?

UBIFS: mount based on UUID?

[Wolfgang Denk]

Hi,

is there any way to mount UBIFS based on the UUID like we can do for
"normal" file systems, i. e. by using "UUID=..." instead of a device
name in /etc/fstab ?

I see there is a UUID in the file system's super block, but I can't
see it is exposed to any sort of regular user interface.

Am I missing something?

Best regards,

Wolfgang Denk

No, you are right, we do have UUID, but we added it just in case we need
it in the future, e.g., for NFS support, but we do not use it currently
because we did not need it. And we did not look at mounting by UUID - it
should be possible to do.

I'm a bit overloaded at the moment, but if I have time later, I can look
at it.

I see. But there is always an option to just do it and submit a patch,
do not forget about this :-)

I said that I may look at this, and this mail is still in my todo box.
But unfortunately, I've realized that I am unable to do many things I
wanted to. In the past, MTD/UBIFS was very related to my regular work,
but now my work has no relation with MTD/UBIFS, so I do not have much
own time for it. Thus, I am dropping many of my TODO items.

Just wanted to let you know.
