Using Lorax to upgrade a 6.0 system cause a system hang/crash. In the second stage of the install the system hangs while searching installed packages. From the script output a permision error is seen while trying to call makeinode in of the python scripts. So it appears that the script is attempting to write something where it can't
Some more debug info I have found. The error output from the install is File "/usr/lib/python1.5/site-packages/isys.py" Line 63 in makeDevinode return _isys.mkdevinode(name,fn) SystemError (2,No such file or directory); The whole calling chain was displayed.. but I thought was the relevent portion.
By any chance do you have /tmp symlinked to somewhere? There is a problem in the installer (which is really hard to workaround unfortunately) that the installer is not able to follow absolute symlinks. It is fine with relative symlinks, so if you have an absolute symlink, just change it to be a relative one and your install should work fine. I am marking this bug a duplicate of #6141. Please reopen if the symlink change does not resolve the problem. *** This bug has been marked as a duplicate of 6141 ***
