nix develop works OK. But with --ignore-environment I get:
[dpc@localhost-live flakebox]$ nix develop --ignore-environment
/usr/libexec/grepconf.sh: line 5: grep: command not found

What seems to be happening is that environment is wiped, yet bash executes some scripts from system’s /etc/bash_completions.d/... which expect some commands that are not available.
No idea who’s “fault” it is. Should nix start bash that does not call system’s init file? Or is it built in somewhere and hard to avoid?
