Installed RH 7.0 Beta for Alpha on an ES40LP 4-CPU SMP machine.  I 
followed an "everything" setup with a custom disk partitioning using disk 
druid.  I chose the following during setup:

1.) Graphic login using KDE as my windowing system (init 5).
2.) Elsa Gloria graphics.
3.) DHCP so localhost is hostname.
4.) "everything" installed.
5.) Created a regular user account in my name.
6.) Boot an SMP kernel.

Note: I did NOT change any configuration files or changed any defaults 
that were done by the installer before seeing the problem below.  All 
changes to this machine are noted below.

After the setup was complete, I booted the Alpha and logged in as root.  I 
immediately wanted to learn my dhcp IP address and ran "ifconfig" from my 
root prompt.  It failed and said "command not found".  I found that all 
the commands found in /sbin do not work UNLESS I call them from their full 
pathname.  "/sbin/ifconfig" works fine.

** I then did an "mv /etc/securetty /etc/securetty.old" to allow remote 
root login.

I did the following tests to see what the behavior was:

1.) I remotely logged into this Alpha from another RH6.2 Alpha system. 
After logging in, I made an "ifconfig" call, it ran fine without having to 
explicity give the full path. I did this with telnet and rlogin from the 
rh6.2 system.

2.) I remotely logged into this Alpha from a Konsole terminal ON this 
Alpha.  Again, the plain "ifconfig" call ran fine without giving the full 
path.

3.) I changed my "/etc/inittab" file to only boot to runlevel 3.  I 
rebooted the Alpha.  I logged in at the console and again the "ifconfig" 
command ran fine without the full path.

4.) From runlevel 3, I did an "init 5" and brought the Alpha to graphics 
login.  I logged in and then "ifconfig" failed again.  I needed to give it 
the full path once again.

That's it...
