Description gregor 2010-02-13 20:23:07 UTC
Zusammenfassung:

SELinux is preventing /bin/bash "read" access on /home.

Detaillierte Beschreibung:

SELinux denied access requested by Default. It is not expected that this access
is required by Default and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Zugriff erlauben:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2010-02-14 15:02:33 UTC
You have setup /home to point at a different directory?  Where is this other directory?  

Have you considered bind mounts.

Comment 2 gregor 2010-02-14 19:29:10 UTC
yes /home points to another directory.
/home -> /mnt/daten1/linux/home/

/mmt/daten1 is mount via fstab:
/dev/VolGroup00/LogVol02 /mnt/daten1             ext3    defaults        1 2

Hi I dropped the ball on this one.  Lost in the flood of bugzillas.  Are you still seeing this problem?

Comment 4 Bug Zapper 2010-11-03 22:10:32 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
