Since SIGTERM is catchable, your code should nicely clean itself up.

normally as a part during reboot/shutdown procedure, sigterm is sent

So these files are preserved.  But when the system goes down because of a
power glitch, there are chances that you lose your data from last filesystem
sync.

I have several running daemons  that write some data to files
What happens with these open files when INIT 6 command  is issued?
Are these files that are used by daemons deleted? Or are they closed
regularly and saved ?
And what happens, if the  Linux box is shut down in a dirty way( out of
electricity)?
