Subject: [PATCH] scripts/gen-btf.sh: fix shebang for NixOS
Date: Tue, 20 Jan 2026 18:20:33 +0000 [thread overview]
Message-ID: <20260120182034.3647092-1-gary@kernel.org> (raw)
From: Gary Guo <gary@garyguo.net>
NixOS only puts /usr/bin/env and /bin/sh at the standard location as
required by POSIX, but not other shells. Other program that kernel build
depends on is supplied via PATH, so shebang needs to use /usr/bin/env to
find them.
This has been done to a few other scripts already, e.g.
gen_test_kallsyms.sh or decode_stacktrace.sh.
Fixes: 522397d05e7d ("resolve_btfids: Change in-place update with raw binary output")
