Describe the bug

As noted in the package description, "This package does not work on NixOS". This bug documents the issue.

> nix-shell -p bazelisk

$ cat .bazelversion
6.1.0

$ bazelisk version
Bazelisk version: development
2024/05/07 19:29:17 could not run Bazel: could not start Bazel: fork/exec /home/craig/.cache/bazelisk/downloads/sha256/6c25a6d716545d6b672ec46f770521cd9ebb63d73617b8f4e6747825d1db1839/bin/bazel: no such file or directory

$ ls -al /lib64/ld-linux-x86-64.so.2
ls: cannot access '/lib64/ld-linux-x86-64.so.2': No such file or directory

bazelisk pulls down a binary which is expecting the system dynamic linker at /lib64/ld-linux-x86-64.so.2 and gives the confusing "file not found" error.

Patching the interpreter...

$ patchelf --set-interpreter /nix/store/apab5i73dqa09wx0q27b6fbhd1r18ihl-glibc-2.39-31/lib/ld-linux-x86-64.so.2 /home/craig/.cache/bazelisk/downloads/sha256/6c25a6d716545d6b672ec46f770521cd9ebb63d73617b8f4e6747825d1db1839/bin/bazel

That's as far as I can take it. Maybe we should patch bazelisk to do the necessary patching of any downloaded binaries?

As a workaround, I point people to the Nix package versions project. You can find a few more versions not listed there, for example you can get version 6.1.0 with nix-shell -p bazel -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/be9859e8994910156989cb842a373541fde19bb1.tar.gz

Should bazelisk create a FHS ?
