Subject: [PATCH] libstore/static-init: don't crash if nixBinDir exists but
 isn't accessible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In d2696cdd¹, libstore was made to prioritize NIX_BIN_DIR/nix (over
/proc/self/exe) if it exists. But `pathExists()` throws an exception if
lstat() returns any error other than non-existence.

Because this check happens in libstore's Settings constructor for the
static-initialized global `nix::Settings`, this case would abort Lix
well before main().
