using flash drive changes device /dev/sr0 to /dev/sr1 for mapping to /dev/pktcdvd/0?
 

Installed udf packet writing to external, USB DVD+RW. Works allright except after using memory stick in the USB hole - it only has one hole (into each life ....) After doing this the drive's device name changes from /dev/sr0 to /dev/sr1, I think.

Since the computer thinks that /dev/pktcdvd/0, the packet writing special device, is mapped to /dev/sr0 package writing no longer works. This can be remedied by re-booting.

Is there a more convenient way of getting package writing back than rebooting. Tried, on the off chance, MAKEDEV; it makes /dev/.static/pckcdvd0, etc..

If the answer has something to do with pktsetup, this does not seem to work - trying 'pktsetup /dev/pktcdvd/0 /dev/sr0' or some variant of this gives ioctl: Inappropriate ioctl for device. When the pktcdvd0 device is created. Thanks any help.

I would think your best bet would be to write some udev rules for the devices, so they always get the same device name..

Thanks, you're probably right but it sounds like hard work. Anyway I'll read the link, thanks again.

Something like:

# /something/init.d/udftools start

does it, i.e. the thing that runs on startup.

Using a soft-link, courtesy of udev that always points to the DVD/RW doesn't. Do not know why.
