Fresh install of BETA2: console error about a LOR...

[Julien Gabel]

Hello,

During the configuration phase, just after installing 6.0-BETA2 on a
notebook, i got the following message on the console:

The machine is already up (no panic, no hang, no shutdown).  When it
happened, i was in the process of editing configuration files remotely
with a build of net/cvsup-without-gui using the traditional way (i.e.
'make install').

If somebody is interesting in testing something or get more information,
the machine is ready to test what may be necessary.
