/bin/sh not found

[Joel Andres Granados <jgranado redhat com>]

Hi all:

Been working on anaconda for almost a month and I have used the shell 
that is on tty2 to look at log messages and whatnot.  On Friday the 
shell simply stopped working.  I tried to look for it in tty2 and it 
wasn't there.  At first I thought it was the type of installation, so I 
decided to kickstart it into text mode.  Didn't help at all.  I entered 
the pythons debuger to see if I could find anything interesting:
1. The os.access("/bin/sh", os.F_OK) returned False & and the 
os.access("/sbin/sh", os.F_OK) returned False as well.
2. When I os.listdir("/bin") it lists sh as being inside the directory, 
this also happens with os.listdir("/sbin").
3. Looked at the anacdump.txt and saw an ERROR that read "cannot open 
shell - /bin/sh doesn't exist."

I'm pretty sure that the ERROR message is from the loader.c file but 
have no clue as to way the /bin/sh is not found.  Moreover seems very 
strange that the os.listdir() lists the file and the os.access() does 
not see it. 
Anyone know a way out :(
any comment is greatly appreciated

Regards
Joel
