Subject: Re: bug#30994: bug#45857: 28.0.50; Not possible to set
 package-user-dir in early-init.el
Date: Fri, 22 Jan 2021 16:08:27 +0000

I am still getting start up package.el oddities. While I can reset
package-user-dir in early-init.el now and it is correct when init.el
starts up, my package-initialize is raising an error from auctex in my
case.

    Warning (initialization): An error occurred while loading ‘/home/phillord/.emacs.d/init.el’:

    File is missing: Cannot open load file, No such file or directory, tex-site


package-user-dir looks right

    package-user-dir is a variable defined in ‘package.el’.
    Its value is "~/.emacs.d/elpa/28.0"
    Original value was "~/.emacs.d/elpa"

but load-path is not correct, having been set up for the default
location of package-user-dir


load-path is a variable defined in ‘C source code’.
Its value is
("/home/phillord/.emacs.d/elpa/auctex-13.0.3" "/home/phillord/.emacs.d/elpa/cider-1.0.0" "/home/phillord/.emacs.d/elpa/clojure-mode-5.12.0"
