Hi all,
Any suggestion to fix these kinds of QA warnings?
libpam is referencing /usr/lib/libcrack from /lib/security.
I tried to fix cracklib to install to /lib but cracklib is using other
libraries from /usr/lib, I am afraid that I am touching a chain, so any
good ideas?
Historically I'm used to cracklib being in /lib... but I also don't
remember a huge chain of additional libraries.
libcrack is depending on libz and libz is in usr/lib too.
Seems libz didn't depend another.
What exactly reason that this is a serious problem? Is this a standard?
It is quite possible that a lib library depending on usr/lib then .....
Do we have a one-shot cure?
The QA message is because the / (non-/usr) was originally designed to be the
minimal boot environment, and then /usr would be added to provide the full
system capabilities. There are some advantages to this behavior for embedded
systems, as it can allow for smaller footprint systems to be the boot environment.
With modern components like udev, systemd, and such, sometimes it's difficult,
if not nearly impossible to have this split though, as many of the components
require libraries and/or binaries that normally reside in /usr. Generally we
have the choice to either move the libraries or binaries, or break the
dependency on those items (by changing the configuration, statically linking, or
changing the behavior so the library/binary is no longer needed.)
I suspect libz is needed because the cracklib dictionary is compressed.
Dependending on usage, it may make sense to statically link libz into libcrack,
and move libcrack to /lib.

It may be worth identifying the chain and seeing if we can break it,
or at least reduce it in some fairly easy way.
