In theory, programs in /bin are statically linked, so they work even
when you have library issues going on. Anyway, just use the vim command
explicitly or add alias vi=vim to your ~root/.profile
The static linking part is no longer true:
[root@bend ~]# ls -l /bin/vi
-rwxr-xr-x 1 root root 628808 May 9 2007 /bin/vi
[root@bend ~]# file /bin/vi
/bin/vi: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux
2.6.9, stripped
I would guess that any shared libraries used by vi are in or under
/lib. That way the required libraries should also always be available.
Just for comparison, the executable for vim is quite a bit bigger:
[root@bend ~]# ls -l /usr/bin/vim
-rwxr-xr-x 1 root root 2817056 May 9 2007 /usr/bin/vim
This is just another example of the upstream distribution being very
conservative for possibly several different reasons. There are also a
number of ways to override their choice. I just wanted to point out
that the change from vim to vi for root was intentional. Someone
changing it back should understand the implications of what they're doing.
Cheers,
Dave
