Daniel,
After updating another machine (F7 -> F8), I still get gdm failures due to selinux, as originally reported. The problem has not be fixed by recent rpms. See below:
[root@titus log]# rpm -qa | grep selinux
libselinux-python-2.0.43-1.fc8
selinux-policy-devel-3.0.8-64.fc8
libselinux-devel-2.0.43-1.fc8
selinux-policy-3.0.8-64.fc8
selinux-policy-targeted-3.0.8-64.fc8
libselinux-2.0.43-1.fc8
[root@titus log]# ps ax | grep gdm 2264 ? Ss 0:00 /usr/sbin/gdm-binary -nodaemon 2355 ? Ss 0:00 /bin/sh /etc/gdm/XKeepsCrashing 2372 ? S 0:00 /usr/libexec/gdmopen -l /bin/sh -c /etc/gdm/XKeepsCrashing -noopen 2373 tty7 Ss+ 0:00 /bin/sh /etc/gdm/XKeepsCrashing -noopen 2779 pts/0 S+ 0:00 grep gdm
[root@titus log]# audit2allow -i messages
...snip...
#============= xdm_t ==============
allow xdm_t default_t:file write;
allow xdm_t initrc_tmp_t:dir { getattr search setattr };
#============= xdm_xserver_t ==============
allow xdm_xserver_t initrc_tmp_t:dir { write remove_name getattr search
add_name };
allow xdm_xserver_t initrc_tmp_t:sock_file { create unlink };
Disabling selinux lets gdm / xorg run correctly.
I tried removing all selinux rpms, rm -rf /etc/selinux, re-installing selinux, and touching /.autorelabel. No better.
