Full Discussion: Root user
Operating Systems AIX Root user Post 302264988 by bakunin on Friday 5th of December 2008 09:48:58 AM

Generally speaking (this is not limited to AIX) every user with a user-id of 0 (zero) becomes a de-facto root user with a different login name and a different $HOME.

Still, as ravager already said, this arises several problems and is NOT recommended practice. I suggest you explain what you really want to achieve and probably there are other - better - ways to do this.

One problem for example is that several tools get their information from /etc/passwd and implicitly rely on this database being unambigous. "ls", for instance, is one of these tools: if you issue an "chown myadmuser file" for some root-equivalent user "myadmuser" with UID 0 and then do an "ls -l" you will see that the owner si displayed as "root" - simply, because "root" si the first entry to match UID 0 in /etc/passwd.

I hope this helps.

logindevperm

logindevperm(4) 						   File Formats 						   logindevperm(4)

NAME

       logindevperm, fbtab - login-based device permissions

SYNOPSIS

       /etc/logindevperm

DESCRIPTION

       The  /etc/logindevperm  file  contains  information  that is used by login(1) and ttymon(1M) to change the owner, group, and permissions of
       devices upon logging into or out of a console device. By default, this file contains lines for the keyboard, mouse, audio, and frame buffer
       devices.

       The owner of the devices listed in /etc/logindevperm is set to the owner of the console by login(1). The group of the devices is set to the
       owner's group specified in /etc/passwd. The permissions are set as specified in /etc/logindevperm.

       Fields are separated by TAB and/or SPACE characters. Blank lines and comments can appear anywhere in the file; comments start with a  hash-
       mark, ` # ', and continue to the end of the line.

       The first field specifies the name of a console device (for example, /dev/console). The second field specifies the permissions to which the
       devices in the device_list field (third field) will be set.  These permissions must be expressed in octal format.  For  example,  O774.	 A
       device_list  is	a  colon-separated list of device names.  Note that a device name must be a /dev link.	A device entry that is a directory
       name and ends with "/*" specifies all entries in the directory (except "." and ".."). For example, "/dev/fbs/*" specifies all frame  buffer
       devices.

       Once the devices are owned by the user, their permissions and ownership can be changed using chmod(1) and chown(1), as with any other user-
       owned file.

       Upon logout the owner and group of these devices will be reset by ttymon(1M) to owner root and root's group  as	specified  in  /etc/passwd
       (typically other). The permissions are set as specified in the /etc/logindevperm file.

FILES

       /etc/passwd     File that contains user group information.

SEE ALSO

       chmod(1), chown(1), login(1), ttymon(1M), passwd(4)

NOTES

       /etc/logindevperm provides a superset of the functionality provided by /etc/fbtab in SunOS 4.x releases.
