Is madvise critical to run boltdb? I am currently trying to access boltdb on an embedded device running Linux/armv7 and running into this error, madvise: function not implemented. I would rather not recompile the kernel if I can help it. I don't need boltdb to be "fast" just functional on this device. Can this error be skipped/ignored?

I can confirm that ignoring that error (https://github.com/boltdb/bolt/blob/master/bolt_unix.go#L66) instead of returning does allow boltdb to successfully write. Is there any harm in ignoring this error?

Sounds like it could ignore ENOSYS explicitly -- not just any error, that would hide bugs.

You can check if CONFIG_ADVISE_SYSCALLS is set to "y" in your kernel configuration.
Without it, madvise syscall would fail with the error as reported here.
