Hello,

While configuring a machine setup for building the packages remotely, I
observed that all substitutes were first retrieved on the local host.

Since the intent is to deploy the remote machine and have it build the
package itself, this is a wasteful use resources.  The remote machine
should fetch the or substitutes or package sources itself.

Thanks,

Maxim

I'm not sure the above is accurate because near the end of deploy it
only transferred a handful of megabytes.  I suspect it needed something
to compute the derivations locally, perhaps grafts?  For example, I have
openjdk installed on the remote machine, and it was downloaded locally
(more than 100 MiB download IIRC), but it was never transferred, if I
followed correctly.

Sorry to write confusing things; I'm a bit confused myself :-).

Thanks,

Maxim

Yeah, I’m tempted to tag it as “notabug”.  WDYT?

Fine by me, closing for now.

Thank you!
