Title: sys-apps/s6 2.8 ftrig ABI change |

The 2.8 release of s6 includes a bugfix for the ftrig notification framework |
| 15 |
which breaks the internal ABI. Thus 2.8 clients may not receive notifications |
| 16 |
from a pre-2.8 server. |
| 17 |
|
| 18 |
This affects the s6-ftrig-* tools as well as the service state |
| 19 |
notifications provided by s6-supervise. If you rely on these (in |
| 20 |
particular by using s6-svlisten/s6-svwait or s6-rc), freezes will ensue. |
| 21 |
|
| 22 |
It is therefore recommended to shut down all s6 supervision trees before |
| 23 |
upgrading to s6 2.8.0.0. This may not be an option if you use s6-svscan |
| 24 |
as PID 1; in this case stop as many services as possible, perform the |
| 25 |
upgrade and then reboot your system, killing all hanging |
| 26 |
s6-svlisten/s6-svwait processes manually. |
