On FreeBSD the option -a is not usable with the install command since it attempts to overwrite libraries in ${GOROOT}(/usr/local/go).

What did you do?

% cat main.go
package main
import "fmt"
func main() {
	fmt.Printf("abc\n")
}
% go install -a -v .
runtime/internal/sys
go install runtime/internal/sys: open /usr/local/go/pkg/freebsd_amd64/runtime/internal/sys.a: permission denied

What did you expect to see?

all required modules from ${GOPATH} listed as in go build -a, but excluding any ${GOROOT} modules; and the program compiled and installed in ~/${GOPATH}/bin

What did you see instead?

attempt to rewrite file in ${GOROOT} which failed as all files there are owned by root.

Does this issue reproduce with the latest release (go1.9.2)?

I used pkg to install the go14 bootstrap and the FreeBSD port (lang/go) to compile and upgrade:

runtime/internal/sys
go install runtime/internal/sys: open /usr/local/go/pkg/freebsd_amd64/runtime/internal/sys.a: permission denied

Result is the same; tries to overwrite ${GOROOT} file

Thanks for the report. This is fixed on tip by https://golang.org/cl/75850, and the fix will be in the future Go 1.10 release. Closing this issue because at this point we aren't going to change anything in earlier releases. The workaround is to not use -a; it rarely does what you want anyhow.
