| Should all Gentoo init scripts have a 'reload' function to re-read the daemon's configuration without interupting the service? |

 |
|
One thing I'm *really* missing in Gentoo is this nice 'reload' function that (almost) all Debian init scripts have. I have two servers, one Gentoo and one Debian, and it's really nice if I can just start '/etc/init.d/apache2 reload' or '/etc/init.d/jabber reload' to re-read the config file instead of having to do this manually. I know I can do this by sending SIGHUB to the daemon, but it doesn't work for all daemons and it's way easier to do this via an init script. Also, the 'restart' function has the same effect, but it stops and starts the daemon, which is really not very nice if you do this with sshd on a remote machine, like it happened to me once 
I think it should not be much of a problem to add such a function to all the init scripts for the daemons that support it. This is somethng I'm really missing, so I'm voting for inclusion into the Gentoo baselayout!!

| Sounds like something that could be implemented .... file a bug at https://bugs.gentoo.org if you want to see it. |

Well I filed a bug report for this, I already got an answer that wasn't too positive, I was told that such a thing would be the decision of every single package maintainer. I hoped someone could make this a common suggestion/guideline for init scripts

I've always used
| Code: | | /etc/init.d/apache2 restart |
Does this not do what you're asking? I believe it also works for almost every other script in init.d as well.
Maybe I'm missing something, but I hope this helps

actually that stops the service and turns it back on. the idea is to do this without stopping the service. |

Well it would, it would be a big job to go through all the packages that create init scripts and change them, but the package maintainers can do it easily.
There isn't really any sane way of forcing them to adopt this, but it would be a good thing for them to do. If they feel kind.

I must be missing something. This works perfectly for me and I have been using it for a while:
| Code: |
# cd /etc/init.d
init.d # ./apache2 reload
* Reloading apache2... [ ok ]
|
and if you take a look at the apache2 script, you can see the reload function does a graceful restart (apache's way to do what you describe).
Every package does a reload a little different. Some do a SIGHUP, others (like apache) do a -graceful, and some don't do it. There is no way to do a generic way for everyone, fortunatelly, most common daemons have it. |
