As I already wrote, you need to modify the <zoneroot>/dev/null file from the global zone with zoneroot being the directory where your zone is installed.
Sorry, maybe I was unclear on that point. I did the chmod on the /dev/null file of the zone from inside the global zone. The /dev/null file of the global zone itself got the right permissions and is a link to the pseudo device file. However, the file of the zone keeps getting its permissions changed back to the wrong state right away and I'm pretty positive that it's not something 'homemade' (like a users script), just havn't figured out yet where to search for the source.

Maybe it's an stupid question but remeber... I'm Junior..
I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"... (1 Reply)

getzonenamebyid
getzoneid(3C) Standard C Library Functions getzoneid(3C)
NAME
getzoneid, getzoneidbyname, getzonenamebyid - map between zone id and name
SYNOPSIS
#include <zone.h>
zoneid_t getzoneid(void);
zoneid_t getzoneidbyname(const char *name);
ssize_t getzonenamebyid(zoneid_t id, char *buf, size_t buflen);
DESCRIPTION
The getzoneid() function returns the zone ID of the calling process.
The getzoneidbyname() function returns the zone ID corresponding to the named zone, if that zone is currently active. If name is NULL, the
function returns the zone ID of the calling process.
The getzonenamebyid() function stores the name of the zone with ID specified by id in the location specified by buf. The bufsize argument
specifies the size in bytes of the buffer. If the buffer is too small to hold the complete null-terminated name, the first bufsize bytes of
the name are stored in the buffer. A buffer of size {ZONENAME_MAX} is sufficient to hold any zone name. If buf is NULL or bufsize is 0, the
name is not copied into the buffer.
RETURN VALUES
On successful completion, getzoneid() and getzoneidbyname() return a non-negative zone ID. Otherwise, getzoneidbyname() returns -1 and sets
errno to indicate the error.
On successful completion, the getzonenamebyid() function returns the buffer size required to hold the full null-terminated name. Otherwise,
it returns -1 and sets errno to indicate the error.
ERRORS
The getzoneidbyname() function will fail if:
EFAULT The name argument is non-null and points to an illegal address.
EINVAL A zone with the indicated name is not active.
ENAMETOOLONG The length of the name argument exceeds {ZONENAME_MAX}.
The getzonenamebyid() function will fail if:
EINVAL A zone with the specified ID is not active.
EFAULT The buf argument points to an illegal address.
