Hello, here's a draft for a news item I'd like to publish before bumping sys-apps/s6 to 2.8.0.0:
Title: sys-apps/s6 2.8 ftrig ABI change
Author: Luis Ressel <[email protected]>
Posted: 2019-03-??
Revision: 1
News-Item-Format: 2.0
Display-If-Installed: <sys-apps/s6-2.8.0.0
The 2.8 release of s6 includes a bugfix for the ftrig notification framework
which breaks the internal ABI. Thus 2.8 clients may not receive notifications
from a pre-2.8 server.
This affects the s6-ftrig-* tools as well as the service state
notifications provided by s6-supervise. If you rely on these (in
particular by using s6-svlisten/s6-svwait or s6-rc), freezes will ensue.
It is therefore recommended to shut down all s6 supervision trees before
upgrading to s6 2.8.0.0. This may not be an option if you use s6-svscan
as PID 1; in this case stop as many services as possible, perform the
upgrade and then reboot your system, killing all hanging
s6-svlisten/s6-svwait processes manually.
