M-x getenv PATH RET shows "bin"s in other paths, but not "/bin":

/gnu/store/hk4f641r18vpj44m42pny6rp1nwg3d4w-glib-2.56.3-bin/bin:/home/sirga=
zil/.guix-profile/bin:/home/sirgazil/.guix-profile/sbin:/run/setuid-program=
s:/home/sirgazil/.config/guix/current/bin:/home/sirgazil/.guix-profile/bin:=
/home/sirgazil/.guix-profile/sbin:/run/current-system/profile/bin:/run/curr=
ent-system/profile/sbin

"/bin/sh" exists in the system, though:

    $ ls -l /bin
    total 4
    lrwxrwxrwx 1 root root 62 may  6 06:19 sh -> /gnu/store/qn1ax1fkj16x280=
m1rv7mcimfmn9l2pf-bash-4.4.23/bin/sh

M-! sh RET results in "command not found":

    /gnu/store/qn1ax1fkj16x280m1rv7mcimfmn9l2pf-bash-4.4.23/bin/bash: sh: n=
