Hi all,
Just a quick note that I seem to have confirmed this as a SELinux/sudo
interaction issue.
I re-booted my system this morning, with SELinux enabled using the
targeted policy, which is the default for FC3.
I was then able to confirm the behavior that Manuel initially reported
here.
As a result, I have filed a bug report with Fedora's Bugzilla against
sudo:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=156086
and we'll let the FC folks take it from there.
Needless to say, I am now back with SELinux disabled...
Presumably we can now close out the R bug report.
HTH,
Marc Schwartz
