This is my $PATH in zsh:
/home/brown/bin:/home/brown/.local/bin:/home/brown/.guix-profile/bin:/home/brown/.guix-profile/sbin:/run/current-system/profile/bin

$ which -a sudo
/run/current-system/profile/bin/sudo

BUT!

$ ls /run/setuid-programs/
dbus-daemon-launch-helper  newuidmap  pkexec                 sudoedit
fusermount                 passwd     polkit-agent-helper-1  umount
mount                      ping       su
newgidmap                  ping6      sudo

So it looks like it's a problem with my PATH. While in bash I don't
append /run/setuid-programs to it manually, yet bash recognizes the
setuid programs. I'll probably add /run/setuid-programs by hand but I'm
wondering why doesn't it work by default.

Thanks,
Sergiu
