After a dist upgrade (Debian 9 to Debian 10) some things stopped working. 

For example, `iwconfig`, `losetup`, `ifconfig`, `poweroff`, `pm-hibernate`.

These commands work if I type the full path like `/sbin/iwconfig`

My `PATH` is `/home/<myusername>/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin:/home/<myusername>/.local/bin`

Should I just change the path to add `/sbin` `/usr/sbin` to it?

Equally, emacs does not find `/home/<myusername>/.emacs`, should I just add my home directory to the path?
