Assume you are ssh'd into a machine, and you upgrade sshd or alter the config,
or whatever.  You type:
/etc/init.d/sshd restart

You get an OK, and then !!

If fact, you can't *get* /etc/init.d/sshd to start again!
Just how, exactly, is one supposed to properly use init scripts for sshd remotely?
Comment 1 Martin Schlemmer (RETIRED) gentoo-dev 2002-03-05 13:02:43 UTC
Reason is that sshd do not stop cleanly after update of binary.  You usually
have to manually go "killall sshd && /etc/init.d/sshd zap start" after the

Guess you can add this in a script and run it with "nohup" ?

can this be incorporated into the default init.d/sshd script so that it "just

I'm curious as to why this differs from every other Linux distribution I've ever
used.  Debian has *seamless* sshd updates/upgrades, and so does RedHat.
Additionally, despite the fact that I'm sure your proposed solution would work,
I find that it requires too much knowledge specific to Gentoo to pull off.

Actually this is Azarah solution :)

start() {
        checkconfig || return 1
        ebegin "Starting sshd"
        start-stop-daemon --start --quiet --exec /usr/sbin/sshd
  start-stop-daemon --start --quiet --pidfile /var/run/ --startas
        eend $?

It's been tested on my server :)

Just for posterity sake:

The original init file called:
  start-stop-daemon --start --quiet --exec /usr/sbin/sshd
The new one calls:
  start-stop-daemon --start --quiet --pidfile /var/run/ \
    --startas /usr/sbin/sshd
