Summary: SELinux prevented mount from mounting on the file or directory "/mnt/live" (type "dosfs_t"). Detailed Description: SELinux prevented mount from mounting a filesystem on the file or directory "/mnt/live" of type "dosfs_t". By default SELinux limits the mounting of filesystems to only some files or directories (those with types that have the mountpoint attribute). The type "dosfs_t" does not have this attribute. You can change the label of the file or directory. Allowing Access: Changing the file_context to mnt_t will allow mount to mount the file system: "chcon -t mnt_t '/mnt/live'." You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t mnt_t '/mnt/live'" Fix Command: chcon -t mnt_t '/mnt/live' Additional Information: Source Context system_u:system_r:mount_t:s0 Target Context system_u:object_r:dosfs_t:s0 Target Objects /mnt/live [ dir ] Source mount Source Path /bin/mount Port <Unknown> Host (removed) Source RPM Packages util-linux-ng-2.16-10.2.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-41.fc12 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name mounton Host Name (removed) Platform Linux (removed) 2.6.31.5-127.fc12.i686 #1 SMP Sat Nov 7 21:41:45 EST 2009 i686 i686 Alert Count 3 First Seen Thu 12 Nov 2009 09:47:56 PM EST Last Seen Thu 12 Nov 2009 09:47:56 PM EST Local ID a2a6deff-7f05-4073-845c-76e347cfc755 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1258080476.872:32821): avc: denied { mounton } for pid=3031 comm="mount" path="/mnt/live" dev=sda3 ino=1 scontext=system_u:system_r:mount_t:s0 tcontext=system_u:object_r:dosfs_t:s0 tclass=dir node=(removed) type=SYSCALL msg=audit(1258080476.872:32821): arch=40000003 syscall=21 success=no exit=-13 a0=1f70cb0 a1=1f70e40 a2=1f71bc8 a3=c0ed0001 items=0 ppid=2990 pid=3031 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="mount" exe="/bin/mount" subj=system_u:system_r:mount_t:s0 key=(null) Hash String generated from selinux-policy-3.6.32-41.fc12,mounton,mount,mount_t,dosfs_t,dir,mounton audit2allow suggests: #============= mount_t ============== allow mount_t dosfs_t:dir mounton;
Are you mounting a file system on top of a dos file system?
Yes. Is the live cd copied to a vfat partition booted from grub. From grub: title Fedora_12_Beta root (hd0,2) kernel /isolinux/vmlinuz0 root=UUID=48F6-4212 rootfstype=vfat rw liveimg reset_overlay overlay=/LiveOS/overlay--48F6-4212 rdshell rdinitdebug initrd /isolinux/initrd0.img So I can try daily builds of live cd without copy it to a usb.
You can add these rules for now using # grep avc /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Fixed in selinux-policy-3.6.32-45.fc12.noarch
