Re: [systemd-devel] Order-only mount units?

The problem here is that it is not automatically ordered in regards to mounts in the subdirectories or some other dependencies like RequiresMountsFor - that would happen with a mount unit. Add them to /etc/fstab with "noauto" and use RequiresMountsFor. Unless I misunderstand what you need. So the idea would be to add a dummy mount unit with a dependency to the service. like this: [Unit] Description=My dummy mount After=realmount.service [Mount] # What were need to be adapted to what realmount.service does What=* Where=/mountpoint Type=* Options=remount Any thought on this? Without a mount unit there is alot of implicit stuff thats hard to recreate. Another option would be that realmount.service mounts on another path, then the dummy mount unit doing a "bind mount" or move, but I am not sure systemd allows that? Norbert

[systemd-devel] sd_bus_get_timeout returns absolute time despite what's documented
Hi everyone, According to sd_bus_get_timeout(3) man page, sd_bus_get_timeout() returns "timeout in us to pass to poll()" and it also states that "the returned time-value is relative". However, in reality, this function returns an absolute time point (a-ka relative to the monotonic clock epoch). Hence, the returned value cannot be simply converted to milliseconds and given to poll(). It must first be subtracted from the current monotonic clock time. I followed the documentation and had a bug in my code for some time :) Shall the documentation be updated to mention the necessity of conversion from absolute to relative? Or does sd_bus_get_timeout() have a bug and shall this function do the subtraction for the user and return relative time? Thanks, kind regards, Stanislav.
