Hi,

        As demonstrated by

$ ldd /lib/libsemanage.so.1
        linux-gate.so.1 =>  (0xb8092000)
        libsepol.so.1 => /lib/libsepol.so.1 (0xb8015000)
        libselinux.so.1 => /lib/libselinux.so.1 (0xb7ffa000)
        libbz2.so.1.0 => /lib/libbz2.so.1.0 (0xb7fe9000)
        libustr-1.0.so.1 => /usr/lib/libustr-1.0.so.1 (0xb7fbf000)
        libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7e60000)
        libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7e5c000)
        /lib/ld-linux.so.2 (0xb8093000)

	libsemanage1 links to libustr which is located under the,
 possible separate or external, /usr partition, which would render
 libsemanage unusable in such setups. (This dependency has been around
 since 2.0.9).

        Should we move libsemanage1 to /usr/lib? The only reason for it
 to be in /lib would be for early boot, where /usr might not be
 available, but at this point, it is likely not usable without /usr
 anyway.

Yes, I'm not sure why you'd need libsemanage during early boot, we 
probably should apply this:

My only concern with relocating libsemanage is whether it will create
any compatibility problems for existing binaries previously linked
against /lib/libsemanage.so.1.  Also it could get confusing if you build
and install the newer version and existing binaries keep using the old
library at the old location.  You likely need/want to
symlink /lib/libsemanage.so.1 to the new location.

Why does it need to be moved?  Are you doing semanage functions during boot up?

It's moving the other direction (presently in /lib, moving to /usr/lib).
Manoj pointed out that because of the ustr dependency, it no longer
makes sense to keep libsemanage in /lib, because libustr lives
in /usr/lib.

Oh, I misread. I think  like a symbolic link should handle this

Although the only entry I see for this is 

 ls -l /lib | grep '\.\.'
lrwxrwxrwx.  1 root root      14 2009-10-11 07:36 cpp -> ../usr/bin/cpp

Having a symbolic link doesn't help. If someone sees libsemanage.so in 
/lib they should rightly believe that it is available during early boot 
when in fact it is not since /usr/lib/libustr.so might not be available.

The dynamic linker shouldn't really get upset if it moves so the only 
issue is leaving a stale one there on non-package managed systems.

        As long as the new library location is in the ld.so path, there
 is no issue, is there?  At run time, ld.so searches the path, loads the
 shared libraries from the new location, prepares the program to run,
 and then runs it. At worst, there might be two copies of the library
 loaded into memory, in case there are programs already running linked
 with libsemanage.

        If I am wrong, and long running programs might be affected when
 the library location is yanked out from under them, some mitigating
 action may be taken. I am not sure there are any daemons yet linked
 with libsemanage, but I can arrange for any such daemons to be
 restarted during installation, once I get any bug report.

Looks like I missed the libsemanage.so.1 libsemanage.so symlink, applied 
the following patch to libsemanage 2.0.43:
