[opensuse-factory] how to migrate from init.d to systemd
Hi All, I have decided to give a try to systemd... and it seems to work... after one waits 5 minutes or so (hope this bug gets fixed soon). However I have a small script that gets inserted in /etc/init.d/alsasound like this # See how we were called. case "$1" in start) if [ "$PREVLEVEL" = "N" ]; then test -d /proc/asound && start_rest else start_all fi /bin/bash /etc/imic.sh ;; what changes shall I do to make systemd do the same?

Yeah, hope so as well ;). It does not happen for everybody.

None right now ;). systemd calls the "old" init scripts as long as there are no replacements - and there is no replacement for alsasound yet, so the init script is used as is. In general the above is a bad idea since you have to remember changing the file everytime alsasound gets updated, better create a separate file that is dependend on alsasound and starts afterwards Andreas -- Andreas Jaeger, Program Manager openSUSE aj@{suse.com,opensuse.org} Twitter/Identica: jaegerandi SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Indeed, there's alsa-store.service and alsa-restore.service and those will be used now, I didn't notice them before.

Did you file a bugreport against the driver?

Yep, he works on it - but was on vacation and is right now at Desktop Summit, Andreas -- Andreas Jaeger, Program Manager openSUSE aj@{suse.com,opensuse.org} Twitter/Identica: jaegerandi SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
Hi Andreas,
Did you file a bugreport against the driver? I did indeed... this is how I got the workaround for it... I think it i was Takashi...
the hardware in itself is kind of exotic (a macbook pro 7,1) so I do not know if it really deserves all the effort of a proper fix from the devs. Alin -- Without Questions there are no Answers! _____________________________________________________________________ Alin Marin ELENA Advanced Molecular Simulation Research Laboratory School of Physics, University College Dublin ---- Ardionsamblú Móilíneach Saotharlann Taighde Scoil na Fisice, An Coláiste Ollscoile, Baile Átha Cliath ----------------------------------------------------------------------------------- http://alin.elenaworld.net ______________________________________________________________________

Yes.
Something like :
cat << EOF > /etc/systemd/system/default.target.wants/imic.service
[Unit]
Description=Fix the mic
After=alsasound.service
[Service]
Type=oneshot
ExecStart=/bin/bash /etc/imic.sh
EOF
then systemctl daemon-reload
and then test it with
systemctl start imic.service
I didn't test the service file, so errors are left to the readers as an
exercice :)

thank you Frederic, somehow it worked... do not put me to explain why.. .you did the magic..
and then test it with systemctl start imic.service initially I got an error about too few parameters... but after reboot things were ok... and the script was applied...
thank you once more Alin -- Without Questions there are no Answers! _____________________________________________________________________ Alin Marin ELENA Advanced Molecular Simulation Research Laboratory School of Physics, University College Dublin ---- Ardionsamblú Móilíneach Saotharlann Taighde Scoil na Fisice, An Coláiste Ollscoile, Baile Átha Cliath ----------------------------------------------------------------------------------- http://alin.elenaworld.net ______________________________________________________________________
