Description of problem: 
Upgrading a Dell Inspiron 8100 laptop from Red Hat 9. 
 
About 70% of the way through the transfer of the system image from 
the CD to my hard disk, I get an error message to the effect that 
the copy could not be completed and that I am "probably out of disk 
space." Since I know that I have at least 700MB on the / partition 
(more than the size of the iso image), I dismiss the error and try 
clicking next to begin the upgrade again. This is where the 
exception occurs. 
 
Version-Release number of selected component (if applicable): 
 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
1. select upgrade 
2. select update boot loader 
3. click begin upgrade 
4. error message "probably out of disk space" during transfer of 
system image to disk, click ok to dismiss 
5. click next to begin upgrade again 
     
 
Actual Results:  crash 
 
Expected Results:  I would expect a message about how much disk 
space is needed and how much is available if a full disk is indeed 
the problem. Also, the "next" button should be disabled if an error 
has occurred and it is not really possible to continue 
 
 
 
Additional info: 
 
There is a message on virtual console 2: 
"-/bin/sh: relocation error: -/bin/sh: symbol version GLIBC_2.0 not 
defined in file libc.so.6 with link time reference" 
 
If I drop into the python debug shell after the exception and try to 
exec anything in a shell with a command like: 
 
os.system("ls") 
 
I get the same error. If I boot from the cd in recovery mode, I do 
not get shell errors. 
 
The traceback says: 
 
  File "/usr/lib/anaconda/packages.py", line 669, in doPreInstall 
    f = open(instPath + "/etc/mtab", "w+") 
IOError: [Errno 2] No such file or directory: 
'/mnt/sysimage/etc/mtab' 
 
There is a comment in the source at that line about problems with 
old mtabs.
