[Bug 984276] Re: installing casper on a non live system causes update-initramfs to fail

[Tony Brijeski]

This makes more sense.  It would appear this issue might arise after an
install from a usb created remaster that has persistence on.  I will do
some testing of this very scenario tonight and see what happens.  I can
fix this for remastersys but it will still be an issue for folks that do
it manually or using another tool.

Thanks for following up with me on this.  I'll let you know what I find
with my testing.  Colin must have changed this to fix the persistence
issue with usb.  If this is the case I'd add one more check that would
fix the issue for all involved and that would be to check for "/casper".
If it exists then it is running live from usb but if it doesn't exist
then it is a real install.  I'll do some testing with this theory as
well and if it works and doesn't cause issues I can offer up a patch for
Colin to include.

Regards,
Tony
