Bug#1072375: sysvinit: please implement restarting init using triggers

[Aurelien Jarno]

Source: sysvinit
Version: 3.09-1
Severity: important

Dear maintainer,

To avoid issues like #1071462, please implement restarting init 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
