Bug#805771: how to handle first installation

[Daniel Pocock]

Package: libradcli4
Version: 1.2.4-2


Consider whether the preinst script should copy files from
/etc/radiusclient to /etc/radcli if radcli was never installed on the
box before.  Otherwise anybody using a package dependent upon radcli
will have to manually copy or move the files or encounter an outage
after upgrading the dependent package.

The exact way to move those files will depend on upstream feedback about
issues #3 and #5

In particular, should we use sed to replace ipaddr in the dictionary* files?

Should the dictionary* files be under /usr/share/radcli instead?

Should the /etc/radcli/radiusclient.conf be tweaked with sed to refer to
the dictionary file under /usr/share/radcli?
