systemsettings and update

[Claude de Guille]

Hi,
after upgrading 5.0 to 5.1beta via cvs the system seems to ignore my settings 
in /etc/rc.conf and /etc/sysctl.conf.
That means: no hostname is set, no if aliases, no ip adresses assigned, no 
kernel ctl's set, etc...
After switching the settings by hand everything work's as expected.
I'm new to freeBSD so i think i forgot something stupid during that 
updateprozess.  
Any Tip's ?
Thank's
Claude
