Did the upgrade in June ñto Beowuld with fluxbox rather than desktop,
and subsequently upgraded Beowulf twice. No major problems. The
following may not be real problems, but thought best to throw them
out for consideration. I initially had the problem of
occassionally being unable to close a terminal (mlterm), but no longer.


1. .xsession-errors:

xmodmap: unable to open file '/home/haines/.Xmodmap' for reading. Why
no config file?

07:38:37.106 [AWT-EventQueue-0] WARN net.sf.jabref.JabRefGUI - There
seem to be problems with OpenJDK and the default GTK Look&Feel. Using
Metal L&F instead. Change to another L&F with caution.

console.error: itdmanager:

2. dmesg errors

3. fetcmail

The new fetchmail 6.4.0 may have problems. It seeks an SSL
certificate and, finding none, breaks the connection. I worked 
around this by inserting the line 'sslproto " ' into
.fetchmailrc.    

4. exim

The file /etc/exim4/passwd.client could not be read by exim. It
was -rw-r----- 1 root saned 653 Oct 29 12:17 passwd.client
and since I'm in saned group, I should be able to read it. I
changed permissions to -rw-r--r-- to get SMTP authentication.

5. bluetooth

In syslog: Nov 22 06:42:04 engels brltty[724]: DBus error: send
message: org.freedesktop.DBus.Error.ServiceUnknown: The name
org.bluez was not provided by any .service file

Solution was to install bluez

6. dmesg

I find that $ sudo sysctl -w kernel.dmesg_restrict=0 enables
user to run dmesg, but my impression this does not survive a reboot.
Can't reboot now to check.
