Report of in-lieu update UNR9.04 to Alpha 6

[This is more of FYI than a question]

I have updated a current (apt-get update - apt-get upgrade) UNR 9.04 to 9.10/Alpha6 with
update-manager -d

Here are some observations, on top of the bug-reports:

0. It went through rather smoothly, congratulations!
1. cupsd crashed immediately after reboot. Collection of crash data was unsuccessful and abandoned on its own
2. syslogd could not be removed: known bug
3. netbook-applet crashed: known bug
4. Despite all 'cleaning up' on my side, 1147 packages out of the 1538 all together are listed as 'manual' as install status; including aptitude, base-files. This is dangerous: I guess if someone follows some suggestion and removes these, everything will break. I have no clue, where this comes from.
5. It seems, there is no medibuntu yet, which is not surprising
6. gmplayer does not open, no user feedback. On the command line it says:"/usr/share/mplayer/skins/default/skin not found". I have no idea where it went.
7. At printing, cups came with a server error, and the dangerous red 'no entry': "CUPS server error There was an error during the CUPS operation: 'client-error-document-format-not-supported'. I think, the message should go. It had been set to A4 on 9.04, and during upgrade auto-reverted back to Letter. After I set it to A4 manually, it did work.
It is suggested to pop up a message, encouraging the user to set the paper format to an available one, instead.
8. What bugged me, was that many of the icons of the desktop/menu showed in duplicate. Obviously they had been added, and now there was Firefox 3.0 and a Firefox; two identical 'Cheese' icons, and so forth. I was very disheartened that it happened, and that it is impossible to remove any such icon (so it seems) except through the System-Preferences-Menu. I'd for one expect more right-click options there, including 'remove' and 'rename'.
9. There are a bunch of scary messages at boot, betwen grub and the splash screen. I guess though, that these will be worked on, so that the splash screen shows immediately after boot.
10. I had one complete freeze of keyboard and mouse at Thunderbird, clicking on Help-About, and immediately afterwards on a terminal. Could not be reproduced.
