Description Michael Young 2007-07-05 10:47:49 EDT
Whenever I use semodule to add or remove a module or update some selinux
packages I get a lot of errors like
*username* homedir /home/*servername*/misc/*username* or its parent directory
conflicts with a
defined context in /etc/selinux/targeted/contexts/files/file_contexts,
/usr/sbin/genhomedircon will not create a new context. This usually indicates an
incorrectly defined system account.  If it is a system account please make sure
its login shell is /sbin/nologin.

We have a lot of home directories of the form /home/server/misc/user and it
seems that the problem is that genhomedircon is comparing each with the /misc
line in /etc/selinux/targeted/contexts/files/file_contexts and deciding they
match and thus produces an error. I believe the problem is that in the 
checkExists subroutine of genhomedircon the line
if re.search(regex,home, 0):
causes a match if regex fits any substring of "home". I believe you actually want
if re.match(regex,home):
so that it matches from the beginning of the string.

I have seen this with a number of versions of policycoreutils, including the
current one: policycoreutils-2.0.16-6.fc7
