If the problems with the SDC can be solved without a session, it is a
waste of effort and time to arrange a session for it.

Yes, I'm glad that both of you have replied now :-)

Yes, I want to test it, just tell me when it is ready for testing, and I
hope several other people will test it too.

I'm open for both of these alternatives (with and without persistence).
I have tried to get people's opinion about it at the Ubuntu Forums, but
there are not many replies or votes, and there is no overwhelming
indication in either direction. (But most votes and replies indicate
that *something* must be done with the SDC to make it work in a reliable

Maybe there will be more opinion, when your version of the SDC is
uploaded to the repo, Marc. In that case we can help deciding what to do
and maybe help doing it.


One thing we have not yet discussed is re-using the pendrive. It is more
difficult to re-use a pendrive after an iso file is cloned to it,
because there is an ISO 9660 file system, which is read-only.

There are wiping options in mkusb version 10.3. I think one of them
should be added to the SDC, the standard one, that wipes the first
mibibyte and creates an MSDOS partition table and a FAT32 partition.
