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

Working with @latest. Thank you :)
