Is repartitioning possible while one of the partitions is mounted?

[Tim Cussins]

Hi all,

I just spotted post regarding upcoming Runtime Partitioning Support
(http://lists.infradead.org/pipermail/linux-mtd/2010-July/031200.html)

After taking a cursory glance at the patch it's not immediately obvious
( uh, to me anyway :D ) whether you can create/delete partitions while
a filesystem (e.g. rootfs) is mounted from another partition on the same
mtd device.

Under what conditions can you create/delete partitions?

Cheers,
Tim
