We currently ship wpa_supplicant in /sbin so that it can be used early
in the boot process. However, it links against libpcsclite.so.1 which is
in /usr/lib. This breaks things for people with a separate /usr.
Would you consent to moving this library to /lib? The attached patch
implements this change.
I don't think that is the correct solution to the problem.
Moving the library to /lib will allow moving wpa_supplicant in /sbin but
wpa_supplicant will not be able to work with smart card support.
libpcsclite needs to communicate with the pcscd daemon. This daemon is
in /usr/sbin/ and is linked with libhal (and other libs). I don't think
you plan to move libhal (and its dependencies) in /lib.
The correct way to solve this problem is to use dlopen() in
wpa_supplicant and use libpcsclite.so.1 only when needed/requested.
I looked at the wpa_supplicant code and the needed code is already
present. It is in the file wpasupplicant-0.6.9/src/utils/pcsc_funcs.c
Dynamic loading is used in case of __MINGW32_VERSION. I include a simple
patch to use loading at runtime even on Linux.
I have not tested the patch. I have just tested that the compilation
works and that the resulting binary is no more linked with
libpcsclite.so.1.
I think this bug should be reassigned to wpasupplicant, and my patch
sent to wpasupplicant upstream for review.

The way Ubuntu installs pcsc-lite has impacts for users upgrading
pcsc-lite the "normal" way.
Please (re)consider updating wpa_supplicant instead of pcsc-lite.
