Comment # 4 on bug 1216138 from Danny Grenningloh

So, I actually get some more results on this after playing around with NixOS,
where I faced a similar issue.
Turned out that the entire issue is the fact that I can not get an interactive
password prompt. When I change the command and add password=xxxx to the mount
options the command runs fine.
This would mean however that I would need to add the password to the script
that runs the mount command. Not ideal, as I would prefer to not store the
password on the device.

In NixOS I was able to solve this by adding the samba package and adding CIFS
to boot.SupportedFilesystems.
However, I have no idea what the equivalent of that would be in Aeon. Here is
hoping that you do and it is a simple fix.
So, it seems it does work, there is just something missing for full interactive
functionality.
