Description of problem:

posttrans scriptlet has the following lines in it:
.....
restorecon /boot 2>dev/null >/dev/null || :
restorecon /proc 2>dev/null >/dev/null || :
restorecon /dev 2>dev/null >/dev/null || :
.....

Redirection "2>dev/null", instead of "2>/dev/null" is not likely to work outside of one specific location. :-)  In fact does complain "line 8: dev/null: No such file or directory" and so on ...

Version-Release number of selected component (if applicable):
filesystem-3.2-28.fc22
