Apache Traffic Server may use raw disk for caching, and for privilege elevation, the worker process(traffic_server) will setuid to nobody, my question is, how to make traffic_server access the /dev/ada*?
in linux, disk permitting is root:disk 0660, we can go with: 1, setup a new user 'ats', and put it into 'disk' group 2, after setuid, run initgroups() to complete the groups evn. we need a safe and easy to implement way for raw disk access in FreeBSD. thanks for you help -- zym, Zhao Yongming. aka: yonghao @ taobao.com
