Is that true?
That's stone age. That's interrupting. That's simply bad.
Isn't that the bussiness of another OS?
That may be a valid comment, but I believe Moshe is correct. TZ is
only discovered during libc's init() stage, which happens once per
exec() (*not* once per fork).
FWIW, changes to DNS resolvers in /etc/resolv.conf also require a
process restart to get picked up. pfSense hides that somewhat by using
local dnsmasq as the local resolver - and dnsmasq gets restarted. I
don't know of any similar proxy-ish technique for timezones.
If you want to get pedantic, changes to termcap/terminfo don't
[usually] get picked up until process restart, either.
OTOH, I agree with the other interpretation of your comment - that a
controlled "restart all services cleanly" function would be a Very Nice
Thing to Have. I don't know of any OS that encapsulates that in an
easy-to-use button, but in a controlled environment like pfSense it
should be possible to implement.
