This is mostly out of curiosity, but I was surprised by the behavior, so I was hoping somebody might be able to explain why this behavior was chosen. In particular, consider any zombie process, e.g.
$ cat /proc/77078/status Name: test State: Z (zombie) Tgid: 77078 Ngid: 0 Pid: 77078 PPid: 77077 TracerPid: 0 Uid: 1000 1000 1000 1000 Gid: 1000 1000 1000 1000 [...] now, this process has uid 1000, as does the /proc/<pid> directory $ stat /proc/77078 File: '/proc/77078' Access: (0555/dr-xr-xr-x) Uid: ( 1000/ keno) Gid: ( 1000/ keno) but most files in /proc/<pid> are owned by root: $ stat /proc/77078/status File: '/proc/77078/status' Access: (0444/-r--r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Why is this? Why don't these files remain owned by the same uid as the process itself? Keno
