Is it supposed to be possible to run grub-install from the LiveCD with SELinux on?

[Michael Wiktowy]

I am running into a ton of issues trying to get my SiI 3112 RAID1 set
booting. If anyone knows of a guide to the required voodoo to have
this work, please let me know as the f7test3 installer doesn't quite
end up with a bootable system.

Among my problems is that fact that SELinux is clobbering
grub-install. I get a number of the following errors for a bunch of
tmp files, bug or feature?:

Summary
    SELinux is preventing the /sbin/grub from using potentially mislabeled files
    (/tmp/sh-thd-1175367330 (deleted)).

Detailed Description
    SELinux has denied /sbin/grub access to potentially mislabeled file(s) (/tmp
    /sh-thd-1175367330 (deleted)).  This means that SELinux will not allow
    /sbin/grub to use these files.  It is common for users to edit files in
    their home directory or tmp directories and then move (mv) them to system
    directories.  The problem is that the files end up with the wrong file
    context which confined applications are not allowed to access.

Allowing Access
    If you want /sbin/grub to access this files, you need to relabel them using
    restorecon -v /tmp/sh-thd-1175367330 (deleted).  You might want to relabel
    the entire directory using restorecon -R -v /tmp.
