Problems with SL4 migration

CERN IT information:

Problems with the AFS LCG UI at CERN:

02 Feb 2007 : LCG UI version 3.0.10-1:

no account type / shell flavour problem and resolution references
1 any a) /afs/ works only on SLC3, /afs/ works on SLC4 GGUS ticket:
2 any a) /afs/ corrupts python environment=, so python -c "import re; re.compile('')" fails when using local python 2.3 installation , reason: PATH appended so interpreter mixup; GGUS ticket:
b) affects users who source the LCG UI before starting Ganga (e.g. ATLAS), workaround: prepend to PATH /afs/
c) affects internal Ganga GridShell command execution;
Solution: LCG module updated in Ganga 4.2.8 to remove the explicit invocation of python interpreter:
- DO NOT source LCG UI interface before starting Ganga
- Set LCG UI configuration scripts in [LCG] section of your ~/.gangarc file:
Ganga uses these setup scripts to create an internal, isolated grid shell environment to run LCG commands.

10 Feb 2007 : LCG UI version 3.0.12-0:
The environment mixup problems are solved in this version of LCG UI.
