[Message part 1 (text/plain, inline)]

On every startup, emacs is compiling this file for no reason:
Compiling /usr/share/emacs/30.1/lisp/net/tramp-loaddefs.el.gz...
uncompressing tramp-loaddefs.el.gz...
uncompressing tramp-loaddefs.el.gz...done
Compilation finished.
Not sure why this is happening, happened after upgrading from I believe
29.4 to 30.1.

It just says that it compiles, but it really doesn't.  Because
tramp-loaddefs.el has this at its end:

  ;; Local Variables:
  ;; version-control: never
  ;; no-update-autoloads: t
  ;; no-native-compile: t  <<<<<<<<<<<<<<<<<<<<<<<<<<
  ;; coding: utf-8-emacs-unix
  ;; End:

So it attempts to compile it, then sees that it shouldn't, and does
nothing.

This is harmless, and is not a bug.

Emacs 29 did that as well.  Perhaps your Emacs 29 was built without
native-compilation?

Managed to fix it by putting
(setq native-comp-deferred-compilation nil)
in early init.
Looks like arch now includes native compilation in newest emacs

That's completely unjustified.  You disabled JIT native compilation,
so you will be unable to enjoy the faster performance of the native
code.  And you did that to avoid a completely harmless issue.

> Looks like arch now includes native compilation in newest emacs

Probably because native compilation is the default now.

I'm therefore closing this non-bug.
