- What you're seeing is not a bug but a *feature*. If you rlogin or
- telnet from the Unix box into the VxWorks target the first time, your
- whoami works like a champ. However, once you log out of the target,
- VxWorks automatically removes the whoami information as a security
- feature to prevent someone else from accessing the target and becoming
- the user identified in the boot ROMs without executing the "iam"
- function. Of course, these restrictions are trivial and somewhat
- annoying but short of enabling the security option of VxWorks, they
- represent a minor inconvenience only in the name of security.
