Igor,
I changed the text of my email to make it more readable, replacing
"senior" with "admin" as well as the name of my domain and machine.
I'll leave the correct names this time.
Yes, I actually did a recursive chown on everything below /, and it
still doesn't work. I can't really see the permissions on /usr/bin
since it is strangely mounted separately from the other directories in /usr:
