Notes
There are three system groups which cannot be deleted:
[admin@rb13] > /user group print 0 name="read" policy=local,telnet,ssh,reboot,read,test,winbox,password,web,!ftp,!write,!policy 1 name="write" policy=local,telnet,ssh,reboot,read,write,test,winbox,password,web,!ftp,!policy 2 name="full" policy=local,telnet,ssh,ftp,reboot,read,write,policy,test,winbox,password,web 3 name="test" policy=ssh,read,policy,!local,!telnet,!ftp,!reboot,!write,!test,!winbox,!password,!web [admin@rb13] >
