chcon is in the modified fileutils package. But you can also use chsid or setfiles to label existing devfs nodes - all three programs invoke the chsid system call to set the label on a file when run on a SELinux kernel. chcon is merely a nicer interface than chsid that is derived from the existing chmod/chown programs in fileutils.

For filesystems that use the persistent label mapping (e.g. ext2, ext3, reiserfs), the label will set by the chsid call be retained across reboots since it is stored in that mapping. For pseudo filesystems like devfs, the label won't be retained across reboots unless you also add it to devfs_contexts, because there is no persistent storage of the label. So, if you want the labels to persist, you'll need to update devfs_contexts and then reboot.
