 There was no problem in building Firebox 3.6b3 or 3.6b5.  They run
 well, it is merely that the IBM Java plugin does not work


Thanks for your reply Steve.  You've provided a clue regarding an
approach which I previously missed regarding getting complied programs
up and running.

  Just to be explicit, any one Linux computer owned by an individual
  has one and only one root account.  If however there is a family or
  group sharing the computer then there can be multiple user accounts
  each with a user password, but still there is only one root.
 
 Actually, any account with uid 0 will have root privileges regardless
 of username, and you can have as many of them as you want (although
 many consider it a bad idea to have multiple root accounts).
 
 In some unix systems (e.g., BSD, I think), there is a standard second
 root account with username toor (root spelled backwards).  This can
 be handy if you want to use a root account with a non-standard default
 shell that doesn't reside in the root filesystem but leave another
 with a standard shell for use in single user mode or emergencies.
 
 Long ago (in simpler times) I once had an account on a shared system
 (a research machine at a university) on which *all* users were given
 uid 0!

Hi Ray:

What you describe is possible but in my experience such systems with
multiple root designations are development systems.  In other words,
such systems exist within offices or sites where programmers or others
are using or designing code implementing applications either in-house
for a company or university or cooperating together for a group project
to fulfill a contract.  Even in such scenarios, root access was
strictly controlled.

Other than this scenario, as you noted, it is not a good idea to have
multiple root accounts as such access can wreck destructive havoc in any
Unix/Linux environment.  Even if one is very skilled, utilizing only one
root account it can be an annoying challenge when one makes a mistake
and needs to reinstall or reconstruct/repair an entire Linux
installation from scratch.

All the best...
