What would it take to connect at least one OverDrive?  How can the
admins among us help?

Before, when Danny reported issues with emulated builds, we stopped all
emulated builds for AArch64/ARMv7 to avoid further breakage.  So I guess
we should try to get back to that situation.

Nice that it quickly gets better!

Fun.  Not sure what the correct solution would be; perhaps make one
/api/queue request per system type?

Thanks!
