[Pkg-samba-maint] Bug#771689: samba-common: preinst syntax errors

[Andreas Henriksson]

Package: samba-common
Version: 2:4.1.13+dfsg-2
Severity: normal

Dear Maintainer,

While building a new debian jessie docker container I spotted:

Preparing to unpack .../samba-common_2%3a4.1.13+dfsg-2_all.deb ...
/var/lib/dpkg/tmp.ci/preinst: 5: [: =: unexpected operator
Unpacking samba-common (2:4.1.13+dfsg-2) ...

This seems to be caused by the underquoted subshell invocation for readlink.
The file it tries to read is from the samba-common package itself and
thus does not exist on new installs. Just adding quotes around the
subshell in the if on line 5 should fix this.
