[ubuntu-za] Root user in Ubuntu

[Nico Michael(iBurst)]

Hi there

*I need to work as root user *
I need to enable the root user and set the root user password in my 
Ubuntu workstation in a VM
I could do sudu su but I need to login with full root as the root user

*This is in a VM and risks mitigated*
Regarding risks this is a VM so I will make an image in the VMware 
server to recover from damage.

*How do I set root password*
I know is solaris you would use a passwd command to set the root user's 
password

*What is root home directory*
I also know in solaris the root users home directory in not /home/root   
what is it in Ubuntu Linux?
*
**The root or sudo user cant see programs pathed for non-root users how 
do I fix that*
Also I have seen certain program  ran when you logged in as non-root 
user which  did not get pathed and did not run on a Centos Server when 
you logged in as root

*I need to run Sun Java not the non-industry non-standard Java Ubuntu 
provides*
One of the problems all professional Java developers have with Ubuntu is 
we need to use the Industry standard so our programs work Ubuntu tends 
to install its own "Non-Industry non-standard" Java
Which we always have to remove and then it becommes a mission to get Sun 
java to work

*To get Sun Java running on Ubuntu*
I remove the "Ubuntu supplied non-standard Java" then I edit 
/etc/profile and add JAVA_HOME="/usr/lib/jvm/java-6-sun-1.0.0.30 and 
then export JAVA_HOME

*Java does not run as the sudo or root user*
This works when I run      java -version                      I get the 
right version of Java
how ever when I run         sudo java -version            It cant find Java

  which file and or older do you put path information  so the Root or 
SUDO user can find the Java ?


Please advise
