[blfs-support] Su and Sudo--Getting Both to Work

Since I installed 'sudo,' I cannot, when logged in as myself, run 'su.'  
The vast majority of the time, I don't need it, but when building and 
installing using package users, I would like to be able to 'su' to root 
so that I can use my install system.  Before I got X working it wasn't a 
problem.  I just switched back and forth between terminals.  But now 
that X is working, I want to be able to 'su' in xterm.

When I try, I get "Crypt error."  I don't know if it's a 'sudo' or 
'shadow' thing.  I haven't been able to glean anything from the man 
pages.  Oh, I think I can make the appropriate entries in "sudoers," but 
then I'd have to type "sudo su."  If that's the way it is, I'll just 
have to get used to it.

I'd also like to be able to run "halt' and 'reboot' without typing 'sudo 

If this whole thing is just configuring sudo, I'm not sure how to do 
it.  I'm pretty bogged down in the documentation.  I guess I could 
experiment in the chroot environment though.

I will appreciate any tips and pointers.
