ldconfig, /etc/ld.so.cache and prelink ?

[Tom London]

Running strict/enforcing off of Rawhide.

While doing today's rawhide installs (yum),
I monitored the label of /etc/ld.so.cache via
    ls -lZ /etc/ld.so.cache

Several times during the installation of packages,
the label of this file changed from
     system_u:object_r:ld_so_cache_t
to 
     root:object_r:ld_so_cache_t 
[OK, I think]
or to
     root:object_r:etc_t
[Not OK, I think]

Each time it changed to etc_t, I ran
    restorecon -vv /etc/ld.so.cache
a few seconds later and got the typical
     restorecon reset context /etc/ld.so.cache->system_u:object_r:ld_so_cache_t

I'm guessing that when a package updates
/etc/ld.so.cache, it may leave the label
in a funny state, presuming that yum
will fix it at the end.

Does this explain the 'intermittant' prelink
error messages generated during package installations?
