Description Sunny Dubey 2004-12-11 14:55:49 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux; en_US) (KHTML, like Gecko)

Description of problem:
Fix the iptables scriptlet so that it checks for a mounted /proc before issuing any commands.  (This is to prevent from a chroot()'ed install of iptables from issuing commands that might affect the host).

IRC conversation with jbj@redhat as follows;

<jbj> iptables shares global state in the kerenl in spite of chroot. the fix will be to change the scriptlet somehow
<jbj> so scriptlet running in chroot changes the kernel table.
<jbj> perhaps quick and dirty test for /proc mounted in scriptlet is easiest.
<jbj> presuming that /proc is not mounted in chroot.
<jbj> a real test for running in chroot will perhaps need changes to rpm.
<jbj> RFE at bugzilla.redhat.com please so that I don't forget.

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

How reproducible:

Steps to Reproduce:
rpm -ivh iptables* --root /path

Actual Results:  iptables will install ... and the scriptlets will be run (which may cause issues on the host, because they are really being run on the host).

%post only triggers a "/sbin/chkconfig --add iptables".

Where exactly is the problem?

Beats me,     
this was jbj's idea and he requested I submit this bug.
