Description Norm Murray 2008-10-09 06:26:13 UTC

Description of problem:
When starting a tcsh it parses /etc/sysconfig/lang.csh and when executing this line: 
eval `grep -v '^[:blank:]*#' $file | sed 's|\([^=]*\)=\([^=]*\)|setenv \1 \2|g' | sed 's|$|;|'`

tcsh is calling lstat on:
lstat on setenv
lstat on LANG
lstat on "en_US.UTF-8";
lstat on setenv
lstat on SUPPORTED
lstat on "en_US.UTF-8:en_US:en";
lstat on setenv
lstat on SYSFONT
lstat on "latarcyrheb-sun16";
(generated from a printf before the lstat call in glob.c)

Obviously this is incorrect and is not normally a problem, but when a new shell is invoked while cwd is in an automount directory this generates automount attempts which can spam the logs. 

tcsh 6.15 still shows a problem parsing this in context, though the /etc/sysconfig/lang.csh in more recent initscripts has changed so if LANG is already set this line of code is not executed.

nmurray,
  Any word on a fix for this?  Just opened a ticket for RHEL5 and wanted
to check in on status since it will effect both.
