udev is starting too slowly with SELinux enabled, because:

"this is at least partly due to the placement of the matchpathcon_init call in
udev, which causes it to read and process the file contexts configuration in
every child process that it forks rather than happening once in the parent."


This is causing kernel developers to disable SELinux, leading to bugs in their
code when SELinux is enabled by users.

This also seems to be causing significant slowdown on OLPC boards.
