Re: When to reboot after dist-upgrade?

Hi, sorry if this is not the place to ask (and in that case please
point me in the proper direction).

I'm trying to distinguish when a system reboot is an absolute need
and when it is absolutely safe to keep the system running/working
after a `sudo apt-get update && sudo apt-get dist-upgrade`, once
I have already performed a complete restart of all needed services
through `sudo needrestart' options in Debian testing.

In general, if the Kernel is updated, plan to Restart.  Usually, dist-upgrade is required, when Version Numbers change, requiring addition of new packages.  The Linux Kernel is a common (but not the only) reason for this. 

Also beware, because Debian occasionally will update the Kernel without updating the Version Number.  So it is possible that a Restart is required, without a dist-upgrade. 

Good luck!

So, in a situation like this:

$ sudo apt-get dist-upgrade
Reading package list ... Done
Creating dependency tree ... Done
Reading status information ... Done
Calculating the update ... Done
The following packages have been withheld:
   imagemagick inkscape libc-bin libc6 libc6-dbg libcrypt1
libpoppler-glib8 local openssh-client openssh-server
openssh-sftp-server ssh
0 updated, 0 new will be installed, 0 to remove, and 12 not updated.

$ sudo needrestart
Scanning processes...
Scanning processor microcode...
Scanning linux images...

Running kernel seems to be up-to-date.

Failed to check for processor microcode upgrades.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

$ sudo checkrestart
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
Found 6 processes using old versions of upgraded files
(1 distinct program)
(0 distinct packages)
No packages seem to need to be restarted.
(please read checkrestart(8))

, would be perfectly safe and right to keep the system running or on
the contrary should I perform a (warm/cold?) reboot to be safe?

Thanks a lot in advance for any hint or info.

Kind regards.

PS: `apt-get dist-upgrade` output is translated to English..., system is
in Spanish and I keep not-remembering how to force console output
to English, sorry...
