Comments/Problems:

While creating a reproduction for Bug 1141839, I found that if the
installer is preseeded for partman to automatically partition without
confirmation, as done by OpenMediaVault, if the disk is too small, the
installer displays the error message:

If <Continue> is selected, the following error is displayed:

After selecting <Continue>, the same error message is displayed
repeatedly.  There appears to be no way out from this point.  The user
has no way to get back to the main menu to examine the log or start a
shell.  (Esc can be used, but there is no indication of this to the
user.)

It would be great if the installer provided a <Go Back> option from
this screen to return to the main menu.  Ideally hiding the
useless <Continue> button (although I realize detecting that it is
not useful in this case may be difficult).

Thanks for considering,
Kevin
