Bug#1072373: systemd: please implement restarting systemd using triggers

[Aurelien Jarno]

Package: systemd
Version: 256~rc3-7 
Severity: important

Dear maintainer,

To avoid issues like #1071462, please implement restarting systemd by
declaring an interest on the "libc-upgrade" trigger, introduced in glibc
2.38-12. At some point this will allow us to drop the corresponding part
of the libc6 postinst.

Thanks
Aurelien
