[Bug 46722] qtparted fails to save partitions

[Kenny Duffus]

Public bug reported:

This error occurs wether called from ubiquity or on its own

-----------------------------------------------------
Error: Error informing the kernel about modifications to partition /dev/hda1 -- Device or resource busy.  This means Linux won't know about any changes you made to /dev/hda1 until you reboot -- so you shouldn't mount it or use it in any way before rebooti
ng.
Error: Error informing the kernel about modifications to partition /dev/hda2 -- Device or resource busy.  This means Linux won't know about any changes you made to /dev/hda2 until you reboot -- so you shouldn't mount it or use it in any way before reb
ooting.
Warning: The kernel was unable to re-read the partition table on /dev/hda (Device or resource busy).  This means Linux won't know anything about the modifications you made until you reboot.  You should reboot your computer before doing anything wi
th /dev/hda.
Error:
Could not detect file system.
