Currently, the .bashrc skeleton sources /etc/profile.

So, instead of what you suggest, what about having:

  1. /etc/profile and /etc/zlogin (?) both source /etc/environment,
     which uses plain Bourne syntax.

  2. PATH is defined in /etc/environment and includes
     ~/.guix-profile/bin.

  3. The skeleton for ~/.bash_profile sources /etc/profile, /etc/bashrc,
     and ~/.bashrc.

  4. The definition of PS1 is moved from /etc/profile to /etc/bashrc.

  5. The skeleton for ~/.bashrc sources /etc/bashrc.

?

(I was reading the Bash manual to make sure (info "(bash) Bash Startup
Files"), and as an exercise, I’ve cleaned up my own ~/.bashrc and
~/.bash_profile accordingly, which fixes the issue I reported a couple
of weeks ago regarding ‘guix environment’.)

Thanks,
Ludo’.
