What did you do?

Migrated from gokrazy/tools#17.

go run github.com/gokrazy/tools/cmd/gokr-packer -hostname foo -overwrite foo -target_storage_bytes=1153441792 github.com/gokrazy/hello

Compile working with

golang.org/x/sys v0.0.0-20200523222454-059865788121

What did you expect to see?

Compile ok

What did you see instead?

Compiling gokrazy fails when newer x/sys is used:

golang.org/x/sys v0.0.0-20201015000850-e3ed0017c211

# github.com/gokrazy/tools/cmd/gokr-packer
cmd/gokr-packer/parttable_darwin.go:21:33: undefined: unix.SYS_IOCTL
cmd/gokr-packer/parttable_darwin.go:24:33: undefined: unix.SYS_IOCTL

Looks as if unix.SYS_IOCTL has vanished for darwin between v0.0.0-20200523222454-059865788121...v0.0.0-20201015000850-e3ed0017c211. I'll try to bisect.

This looks like #41868.

golang.org/x/sys v0.0.0-20201015000850-e3ed0017c211

This version predates the fix for #41868. Can you upgrade to latest and test again?
