By default, Solaris doesn't allow users to chown files to other users. A sys admin can enable this feature two different ways, or both:

with reboot

  1. add "set rstchown = 0" to /etc/system
  2. reboot
without reboot

  • echo 'rstchown?W0x0' | sudo adb -kw /dev/ksyms /dev/mem

    Doing both will allow the give away feature right away, *AND* after the next system reboot.
    To turn the feature back off, set the variable back to 1.
