We just accept that it will take a few runs before everything gets up to
speed.
First run from cfexecd: binaries are overwritten, cfexecd stays the same
Upon reboot: cfagent gets called directly, which spawns a "new" cfexecd.
Not very elegant, but also not very complicated...requires just two
extra lines of code.

My concern with having cfagent or a child thereof perform the update is
this scenario:
1. cfexecd launches cfagent
2. Something called by cfagent (cf.preconf, shellcommand, proceses, etc)
notices the change and kills cfexecd and cfservd in preparation for
restarting them
3. cfexecd gets the kill signal and exits
4. cfagent gets a signal that cfexecd exited and exits. If it was
performing the change, it exits before cfexecd is restarted.
5. If cf.preconf was performing the change, it gets a signal that
cfagent exited and exits before cfservd / cfexecd is restarted.

If that happens I would have to either resurrect everything via cfservd
or get several people to each log in to a lot of machines to manually
restart it. It is most preferential to avoid the latter :>
The procedure I had in mind was:
1. cfexecd launches cfagent
2. cfagent overwrites cfagent / cfexecd / cfservd with the updated
version.
3. cfagent kills and restarts cfservd
4. cfagent exits
5. cfagent is invoked via cfservd
6. cfagent kills and restarts cfexecd
7. Finish
Has anyone tried that?
Thank you,

Does anyone have any experience with upgrading large
installations of
CFE with CFE? Was there any particular order in which you
pushed the
three components? Are there any gotchas if you are using
cfexecd to
launch cfengine instead of cron?
Is this something you would use "cf.preconf" for?
