/etc/profile contains the following lines: for i in /etc/profile.d/*.sh ; do if [ -x $i ]; then . $i fi done The test should be for read (-r) rather than execute (-x), because source'ing a file reads it. While you're at it, could you also fix /etc/csh.cshrc to use "-r" for this test?
That's not a bug, it's just an easy way to turn it off :)
I would respectfully suggest that there are other ways to turn it off without requiring this broken behaviour (e.g rename to *.sh.x). It is a bug because it's no guard against the conditional action successfully reading the file (ditto for csh.cshrc). Being able to execve() a file is not the same as being able to open() it. I'm not reporting this to be pedantic; I've seen RPMs packaged by people who thought that a script file which is sourced needs read permissions; no more.
Will be fixed in 2.4.11-1; thanks!
