[sane-devel] Systemd support for saned
Louis Lagendijk

Hello,
I have made a simple patch to saned that gives full systemd socket
activation. The big advantage is that it allows debug output to go to
systemd instead of /dev/null. I do however need some changes to
configure.in. I am not sure how to get these in git as I know that I
cannot simply run an autorecof as that kills our ltmain.sh changes.
The autotools on my Fedora 17 seem to be newer than what was used to
generate the current configure etc.
Could somebody give me some hints on how to update the autofoo stuff or
even better do it do?
I would also would appreciate a review of my changes to configure.in, as
we seem no to use pkg-config and AC_CHECK_MODULES a style I am not used
to.
I have attached configure.in and frontend/Makefile.am as well as
saned.c.
Help is very much appreciated
Kind regards, Louis
