XDG_... env variables in root

XDG_... env variables in root

[Hamzeh Nasajpour]

Hi,

I've a weird issue with all `XDG_..` env paths in the `root`. These are `XDG_...` env paths in `user` and `root`, exactly are same:

```
XDG_CONFIG_DIRS=/home/hamzeh/.guix-profile/etc/xdg:/run/current-system/profile/etc/xdg:/home/hamzeh/.guix-profile/etc/xdg:/run/current-system/profile/etc/xdg
XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session1
XDG_MENU_PREFIX=lxqt-
XDG_DATA_HOME=/home/hamzeh/.local/share
XDG_CONFIG_HOME=/home/hamzeh/.config
XDG_SEAT=seat0
XDG_SESSION_DESKTOP=LXQt
XDG_SESSION_TYPE=x11
XDG_CURRENT_DESKTOP=LXQt
XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0
XDG_CACHE_HOME=/home/hamzeh/.cache
XDG_SESSION_CLASS=user
XDG_DESKTOP_PORTAL_DIR=/home/hamzeh/.guix-profile/share/xdg-desktop-portal/portals
XDG_VTNR=7
XDG_SESSION_ID=c2
XDG_RUNTIME_DIR=/run/user/1000
XDG_DATA_DIRS=/home/hamzeh/.guix-profile/share:/run/current-system/profile/share:/home/hamzeh/.guix-profile/share:/run/current-system/profile/share:/home/hamzeh/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share
p
```

Do you have any idea? Where and how can I fix them for `root`?

Regards,

These are doubled because something must be adding them more than 
once.  The generated etc/profile files generally augment existing 
environment variables; they don’t replace them.

I don’t know what this means?  What do you mean by “fix”?

Hi Ricardo,

Thanks for your reply.

Yes, exactly, They are doubled, but another issue is these are env variables in `root`. My main issue is why these variables in `root` point to `USER` paths?

please can you show us only the relevant parts [1] of your bash profile
(or other shell profile) for "user" and "root"?

Thanks, Gio'


[1] I mean the one setting GUIX related env variables

This is my `/etc/profile` content:

Hi,

https://unix.stackexchange.com/questions/7013/why-do-we-use-su-and-not-just-su/7021#7021

>su - invokes a login shell after switching the user. A login shell resets most environment variables, providing a clean base.

>su just switches the user, providing a normal shell with an environment nearly the same as with the old user.


Seems that this is relevant to way of switching user which I used. I was using `su` for switching as `root` and just now I found that there are some differences between `su` and `su -`. With using of `su -` the `XDG_...` env paths are correct:

```
$ su -
$ printenv | grep XDG_
XDG_CONFIG_DIRS=/run/current-system/profile/etc/xdg:/root/.guix-profile/etc/xdg:/run/current-system/profile/etc/xdg
XDG_DATA_DIRS=/run/current-system/profile/share:/root/.guix-profile/share:/run/current-system/profile/share
```

Anyway I didn't know there are differences between `su` and `su -`. 

Regards,
Hamzeh

Yes, that was the issue, I was not thinking about it when I first
replied.
