[systemd-devel] Router Advertisement in systemd

2018-11-05 Thread Daniel Wang
Hi all, Recently I realized that systemd-networkd implements its own Router Advertisement and NDISC. While I am perfectly fine with using it, I wonder what motivated it given that the Linux kernel already implemented both. Is it features? Flexibility? Stability? Also, what else in the ipv6 stack

[systemd-devel] How to add a unit path to systemd?

2018-08-09 Thread Daniel Wang
Hi, I want to append to systemd's unit search path a directory on my OEM partition, which is mounted by a .mount unit, at /usr/share/. I will be putting unit files in that partition, some of which I want to run before default.target. Is it possible to do so without a systemctl daemon-reload? I u

[systemd-devel] When is a unit "loaded"?

2018-07-11 Thread Daniel Wang

[systemd-devel] Is there a way to recover from a crashed systemd without rebooting?

2017-10-31 Thread Daniel Wang
I hit a bug in systemd-232 and it crashed. Anything I tried to do with `systemctl`, including `systemctl daemon-reexec` seemed to rely on the systemd dbus service, which all resulted in `Failed to activate service 'org.freedesktop.systemd1': timed out`. systemd runs as PID 1. Is there any way to r

[systemd-devel] Plan for DHCP Option 119?

2017-04-25 Thread Daniel Wang
Hi all, First of all this is my first email to this list so apologies if it's not worded perfectly. I am wondering if there's any plan to support Domain Search List option in networkd. Some cloud providers like GCE, advertise multiple search domains through option 119 and they just get ignored in
