Description Darcy Christensen 2007-12-11 22:28:22 UTC 
Description of problem:
When querying the file access permissions of a symbolically linked automounted 
directory, particularly -w, from a shell script as root, in RHEL3 the file 
shows as writable when it is mounted as read only.  When the write is 
attempted, of course, it fails.  Apparently RHEL3 uses file premissions behind -
w test where RHEL4, and many other flavors of Linux/UNIX, use the access system 
call, which works correctly.  Is there a work around for this to make this test 
work across multiple Linux/UNIX platforms?

Version-Release number of selected component (if applicable):


How reproducible: Consistantly


Steps to Reproduce:
1.Automount a directory as read only
2.Create a symbolic link to it
3.Write a script testing the -w access (if [ -w dir_name ] ... )
4.sudo as root and run the script
  
Actual results:
directory tests as writable

Expected results:
directory should test as read only

Forgot to mention I work for Oracle and this is a work related issue.
Comment 2 Phil Knirsch 2008-04-16 14:45:21 UTC 
Thats most likely a bash related problem though, so i'm reassigning it to that
component.

Read ya, Phil
