[Netkit.users] Sudo vs Su

[Giovambattista Ianni]

Dear all,

I found that current netkit always uses su for invoking the manage_tuntap 
command, no matter of the USE_SUDO variable value: I'm not an expert of sh 
programming, but I found that the culprit was just a '==' instead of '=' in a 
string comparison.

Hope the attached patch helps: sorry if I post this on the list, I'm not sure 
which is the 'official' way of submitting patches/bugs (nor if this is has been 
already solved)

regards, gb
