For those who don't understand this sentence, libpcsclite1 in sid now
depends on pcscd (which in turn depends on the not-so-welcome hal).
This is the real problem IMO; I don't care about small library packages
as long as they don't drag in random daemons.
After a short coordination with Kel, we've decided to disable PCSC in
the next wpasupplicant upload, which allows to drop the dependency on
libpcsclite1 and therefore indirectly on hal.
Which is the real culprit: why do libpcsclite1 depend on pcscd? This is
#612971 (cc:ed), and I do not understand why it should be fixed on
wpasupplicant side.
Previous versions libpcsclite1 (pre 1.6.0 versions) only had a Suggests:
pcscd
This has been changed to a Depends: in [1].

I think having a Recommends: instead of Depends: is the correct
solution. The pcscd package will be installed automatically in most
cases and can be removed if needed. The Depends: is too strong and not
needed.
libpcsclite1 depending on pcscd now brings hal, but then in future it
will bring whatever pcscd depends on, which is a bit strange for a
library. While I am not a library expert and I understand libpcsclite1
is useless without pcscd, still I do not see why a library depends on a
daemon to be *installed*. And what if someone writes another daemon
different than pcscd, but still for PC/SC communication through
libpcsclite1?
pcscd and libpcsclite1 are two parts of the same project. The source
package is pcsc-lite. They use an ad-hoc protocol to communicate. I do
not think a concurrent libpcsclite1 will ever exist :-)
