[gentoo-user] needrestart - exclude services

[gentoo-user] needrestart - exclude services

[Joost Roeleveld]

Hi all,

After upgrading my system, I always run "needrestart".
This works, mostly, fine. But sometimes I don't pay enough attention  
and accidentally allow a critical service to be restarted, causing the  
server to become unstable.

One of this is "multipathd", which is required for the filesystems.
Another is "xenstored" (which has obvious issues with all the VMs running)

I am unable to find any config files, but am hoping I can add services  
like this to some exclude-list somewhere.
Can someone point me in the right direction?

Many thanks,

---
Joost

I don't know if this will help or not. I use checkrestart to find
services or programs that need to be restarted after updates.  This is
the needed info if you want to try it.  It's in a overlay.

What I like about it, it doesn't restart anything.  It just lists what
needs to be done and you do it manually.  That way if there is something
that shouldn't be restarted, you just don't restart it.  This is a
sample of output, pretty good one too.

To get that I re-emerged sys-apps/util-linux.  It's a package that tends
to trigger a lot of things that need to be restarted, services or
software.  I shortened that list by closing Firefox.  This is a good
example of what it shows and often times what might even require a
reboot.  It will also show if init needs to be restarted.  I tend to use
telinit u to restart init but rebooting works too. 

I might add, I sometimes just use htop to find processes that need to be
restarted.  It uses different colors when services or programs are using
outdated files.  Running checkrestart sometimes takes longer than just
typing in htop and looking at the colors.  The color yellow almost
always means it needs to be restarted. 

As I said, you may like needrestart and just want to tweak it a bit.  Or
this may help.  It may do more of what you want, or not. 

Hope that helps.

I used to use checkrestart until it was removed from the gentoo-tree  
(due to lack of maintenance/updates)
I then switched to needrestart and actually prefer this.
It actually checks the processes instead of what was updated.

Which means the part you showed doesn't actually trigger restart  
requirements as reinstalling the same version won't mark processes as  
running outdated versions.

It also shows me if there is a new kernel or microcode (CPU)

needrestart doesn't restart by default either. It asks, setting the  
default to Y or N depending on if a service can cause run-time issues.
My problem is, the "possible issues" list doesn't seem to be  
configurable. Or if it is, I can't find it.

I didn't know about needrestart, so I installed it. 'man needrestart' lists a 
-c option to specify a config file, but no details. I haven't trawled through /
usr/share/doc/needrestart-* ; have you looked there?

Hello,

My app-admin/needrestart-3.8 installed some files in /etc, like 
/etc/needrestart/needrestart.conf
