Description Lamont Peterson 2007-12-07 00:00:15 UTC 
Description of problem:
KDM and kwin have the ability to cause a 1-time only boot time change to GRUB 
configuration which allows them to provide the option to specify which entry 
to boot to when you select reboot.  This feature is being blocked by the 
selinux-targetted policy.

Here's the text of the denial:
avc: denied { execute } for comm=kdm dev=dm-16 egid=0 euid=0 exe=/usr/bin/kdm 
exit=-13 fsgid=0 fsuid=0 gid=0 items=0 name=grub pid=3281 
scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 sgid=0 
subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 suid=0 tclass=file 
tcontext=system_u:object_r:bootloader_exec_t:s0 tty=(none) uid=0

Bulk closing a old selinux policy bugs that were in the modified state.  If the
bug is still not fixed.  Please reopen.
