No, it does not.

The Arch Linux kernel names don't change. They are always something
like e.g. vmlinuz-linux, never something like e.g.
vmlinuz-4.4.0-140-whatsoever.

When I used GRUB 2, I always edited grub.cfg directly by myself.
However, I migrated to syslinux.

Btw. on my multi-boot machine are Ubuntu flavours installed. Even if
I remove the boot-loader from an Ubuntu flavour install, it likely gets
reinstalled after a release upgrade. I workaround the useless call of
the grub auto-thingy by dpkg-divert, since the bootloader is only needed
by one install.

[root at archlinux moonstudio]# systemd-nspawn -q dpkg-divert --list | grep "local diversion of"
local diversion of /usr/sbin/grub-mkconfig to /usr/sbin/grub-mkconfig.real
local diversion of /usr/sbin/update-grub to /usr/sbin/update-grub.real

The generated grub.cfg contains all kinds of needless crap. It takes
way to long to generate grub.cfg after each upgrade of each installed
distro, simply editing grub.cfg or adding two links (e.g.
vmlinuz-lowlatency -> vmlinuz-4.4.0-140-lowlatency) is less time
consuming. By default the grub auto-thingy fails and editing the
configs for this auto-thingy is rocket science, not KISS.
