[gentoo-user] reload etc conf files

[gentoo-user] reload etc conf files

[laurent]

Hi,

I finished etc-updates with a lot of files, is there a way or even need 
to make all application reload the updated configuration files?

thx
Laurent

Yes, it's called a reboot. Nothing else will get the job done and guarantee 
it's done right without errors.

The better way is to just look at the files that were changed, decide for 
yourself if they need to be restarted and if so restart them manually.

If this reply sounds snarky, it's because your question is actually 
nonsensical from a Unix perspective (although probably quite reasonable from a 
human perspective). This is a situation that requires either a sledgehammer 
approach or intelligent human intervention.

Not quite what you asked, but there's easy way to check if there are
any processes still using pre-update (non-existing now) libs:

  lsof | grep 'DEL.*lib' | cut -f 1 -d ' ' | sort -u

"lsof" here is sys-process/lsof (not part of the @system afaik).

It depends upon the software / changes involved. Many services (eg. web 
server, mail servers) have a "reload" option on the init script (ie. 
/etc/init.d/apache reload), otherwise you generally need to restart them 
to apply changes. Some services / daemons will pick up changes on the 
fly, but generally they don't in my experience.

Programs which are not services / daemons will pick the changes up the 
next time they are run.

You DO NOT generally need to reboot to make sure config changes are 
correctly loaded. This is not Windows. You just need to read the 
documentation for the software involved.

He asked about config files updated via etc-update, not about libs updated via 
emerge

Or send them a SIGHUP - "killall -HUP processname"

Programmers do it bit by bit.
