comment What does the *.*;auth,authpriv.none -/var/log/syslog line mean in rsyslog config file?
It's implied in the documentation above. The priority part is skipped (ignored) for all but the last facility if you list multiple facilities using a comma. The docs could certainly be improved in this area.

comment What does the *.*;auth,authpriv.none -/var/log/syslog line mean in rsyslog config file?
auth,authpriv matches both auth and authpriv. The .none part applies to both of them. *.*;auth;authpriv.none would behave as you describe.

comment How to determine eth0 gateway address when it is not the default gateway?
Interfaces don't have gateway addresses, netblocks do. A gateway address tells the kernel where to forward packets destined for some host on some network. If the address is associated with a given interface then that interface will be used, but the address is independent of the interface.

comment Terminating an infinite loop
@cirosantilli Yes, that's the reason. If a process handles the signal and quits, that's different than the process being terminated by an unhandled signal.

comment Why doesn't setuid on /sbin/dhclient work as intended?
I'm assuming a C program which would call setreuid(), then execve().
