Bug Description

Binary package hint: usb-creator

If I am running usb-creator FROM a live usb system, then the device I am running from should NOT be selectable as a target device since this will lead to a crash.

liveusb already takes care of that:
https://launchpad.net/liveusb

This is already the case by the nature of how usb-creator is designed. To put it another way, because usb-creator searches for devices with the storage.removable property set to true, it will never use the device the live system is running off of.

I've confirmed this in my own tests, but if the disk the live filesystem is running from is present in your tests, please reopen this bug report and print the result of the following command (where volume_uuid_D501_33B3 is the device in question):

dbus-send --system --print-reply --dest=org.freedesktop.Hal --type=method_call /org/freedesktop/Hal/devices/volume_uuid_D501_33B3 org.freedesktop.Hal.Device.GetAllProperties

Thanks

This bug is still present. I am running the 20081022 Live image from a Live USB stick. When I open the usb-creator, the USB stick I am running from is shown in the list of target devices. It should not! Please see the screenshot attached.

Confirmed, but unfortunately too late to fix for 8.10. It will have to wait until the start of the 9.04 cycle.

I spoke with Scott about this and aufs seemingly nukes any information that would allow us to draw a connection between / and a block device in the live environment.

We could take the simple approach of watching out for devices mounted on /cdrom, but that strikes me as being too broad. Still, it's probably worth the risk, given how poorly writing to the block device containing the live filesystem will turn out.
