Description: Tweak defaults values for Debian
Debian needs some default value and a way to compute DriverPath
different from upstream.
.
Debian specific model snippets
are added in comments between {% and %}. This
model snippet is applied after the model generated
from LCDd.conf. Hence these snippets can override upstream
default value. For instance:
.
# {% upstream_default~ default=yes %}
#ReportToSyslog=yes
.
Generated model has upstream_default=yes. This value
is canceled by ' upstream_default~ ' and the default
value is set to yes.
.
DriverPath is more complex. The model snippets adds a way to test and
fix this system dependent value. The fix deletes the DriverPath value
and the compute instructions provide the actual path using Dpkg::Arch
to compute the lib triplet. This requires a runtime dependency on
libdpkg-perl.
.
Device is qute tricky. On Debian, lcdproc package is delivered with a
udev rules that creates a symlink from a rather unpredictable device
file (can be /dev/lcd0 or lcd1 or ...) to /dev/lcd-imon. The model
snippet added to Device ensure that the above symlink is used (if
found) or use /dev/lcd0 as a fallback (which may be wrong though)
.
Protocol value is chosen by running lsusb. If the device is
15c2:0038, then Protocol default value is 1.
