In #debian-devel Michael Biebl only brought up update-rc.d as the problematic
point (maybe there is more). In that case, I had assumed that the fix would
simply be to tell update-rc.d to ignore the presence of /sbin/insserv and
/etc/insserv.conf in case the current system is using systemd. In that case, I
had imagined that the fix is as simple as doing:
--- a/script/update-rc.d
+++ b/script/update-rc.d
@@ -192,6 +192,10 @@ sub create_sequence {
$insserv = "/sbin/insserv" if ( -x "$dpkg_root/sbin/insserv");
# If insserv is not configured it is not fully installed
my $insserv_installed = -x "$dpkg_root$insserv" && -e
"$dpkg_root/etc/insserv.conf";
+ # Ignore the presence of insserv if this system is using systemd
+ if ($insserv_installed && -d "$dpkg_root/run/systemd/system") {
+ $insserv_installed = 0;
+ }
my @opts;
push(@opts, '-f') if $force;
# Add force flag if initscripts is not installed
But I'm not an expert in this matter and I also do not have any motivation to
argue with the systemd maintainers about this. If you have the energy for that
then I can support you with doing the work when things need to be
patched/fixed. In that case, how else can I help you? If you agree that above
is likely correct, then I can build init-system-helpers with this patch and see
if it indeed has the intended effect or not. I suppose to try this out I would
have to install some packages which ship sysv scripts? Do you have a suggestion
for a small/simple package which would be a good candidate?
Thanks!
