e17 is graceful - if you use logout. e17's exit menu does exactly what it says.
e17 exits. simple as that. nothing else is done. generally speaking if e is
your x11 session holder/manager, as is normally the case, the session also
exist meaning your login ends and xserver resets disconnections apps. but this
is not what people really want. that is why a whole system menu exists with
logout, shutdown, reboot, suspend etc. - this is where e17 does the graceful
path, if it can. for shutdown, reboot and logout it first actually walks
through every open window and asks for a "nice shutdown" - the same thing as
hitting "X" on the top-right. apps may ask to be notified of this and have an
opportunity to gracefully close their own window. e will wait around for up to
a timeout (i think 20seconds) and then complain that something is not shutting
down cleanly - you can manually find it then and try again or just say "screw
it" and continue anyway with the "logout". with shutdown and reboot it first
does this logout clean graceful close of all app windows, THEN on logout just
exits e - as above. for shutdown and reboot it uses the sysactions conf to know
what sysaction to pass to enlightenment_sys which is a suid root binary e
installs. this maps the action (shutdown, reboot) to some command to run (eg
shutdown -h now, reboot etc.). the same for suspend and hibernate EXCEPt there
is no logout procedure there. just asks syactions to be run and mapping to who
is allowed, how and what it maps to.
e17 does the graceful right thing. otherwise ymmv :)
