I think there are several things that need to be done to address this
class of bugs:
1. Jockey needs to be more attentive to the lack of space on the root
device. This will be the focus for bug #685017. It should detect the
situation and give the user an error message dialog, without trying to
do the installation.
2. usb-creator needs to not let the user reserve 100% of the space to
documents, or should display an appropriate warning or UI to indicate
that if they do not preserve some space for system files, the usb key
will become non-functional. I recommend something like the following:
* For 1G USB keys, do not offer persistent storage at all
* For 2G to 4G USB keys, make sure there is 800M or so remaining after
creating casper-rw - enough space to update to a new kernel, write initrd, and
other system type things needed.
* For >4G USB keys, put the casper-rw on its own partition separate from the
system files. Ensure there's at least 1G of space for system files, to install
kernels and so on.
