There's no shell, so there's no PATH. You need to specify the path to the executable.

This hook comes with package itself, may you be more verbose about your point?

Re: [Solved] call to execv failed (No such file or directory)

Exec=/bin/echo 'Notice ...'

Though it's interesting that systemd's on man pages (e.g., systemd.service(5)) include examples with Exec=echo which would (wrongly?) imply that it uses execvp rather than execv.

EDIT: technically I suppose that's "ExecStart=" examples, but also notable that "Exec=" doesn't even seem to be a documented option (though there is an example in the man page using it).  Further, countless real examples show that ExecStart= does indeed use execvp (or does it's own path search which is less likely).  So this error seems to be a combination of using a binary name without a path and using an undocumented "Exec=" directive in place of what should be "ExecStart=".  So the real solution would almost certainly instead be the following:

ExecStart=echo 'Notice ...'

I can't verify it just after making the change but hoping that it would work.

No, I was able to verify. It didn't worked

error: hook /usr/share/libalpm/hooks/e4rat-lite-git-update.hook line 8: invalid option ExecStart
error: failed to commit transaction (failed to run transaction hooks)

Re: [Solved] call to execv failed (No such file or directory)

It works with EXEC=/bin/echo

(2/5) e4rat-lite-git-update.hook
NOTICE: Boost has been updated. Please re-build e4rat-lite-git.

Oops! Sorry, this is an alpm-hook not a systemd service file.  They have fairly similar looking ini-syntax but are completely different things.  So (most of) my previous comments are irrelevant: a full path is the only relevant requirement.
