Hi

At what circumstances, slibclean should be used ?


Suppose, I remove a shared library file which is still loaded on global
text segment with the "rm" command and put a new shared library in.
Will program start always reference to the newly loaded shared library
in the shared text segment ? I think installp always rm old files if it
is not an update fileset.


Thanks.

When you need to get the system to stop using a module for
some reason. And the module is no longer in use by any
process.

No problem.

Yes. If the module is in use and you "rm" it, then you remove the
filesystem entry, not the file. The file will get fully removed once
it is no longer in use by the shared lib segment. In the meantime,
creating a new file causes a new inode to be used, and the loader
detects this and loads the new copy. (It keeps track by filesystem/
inode, which is always unique.)
