nixos/tests/installer: Add test for LUKS rootfs. This serves as a regression test for #7859. It's pretty straightforward, except from the fact that nixos-generate- config doesn't detect LUKS devices and the "sleep 60". As for the former, I have tried to add support for LUKS devices for nixos-generate-config, but it's not so easy as it sounds, because we need to create a device tree across all possible mappers and/or LVM up to the "real" device and then decide whether it is relevant to what is currently mounted. So I guess this is something for the nixpart branch (see #2079). And the latter isn't very trivial as well, because the LUKS passphrase prompt is issued on /dev/console, which is the last "console=..." kernel parameter (thus the `mkAfter`). So we can't simply grep the log, because the prompt ends up being on one terminal only (tty0) and using select() on $machine->{socket} doesn't work very well, because the FD is always "ready for read". If we would read the FD, we would conflict with $machine->connect and end up having an inconsistent state. Another idea would be to use multithreading to do $machine->connect while feeding the passphrase prompt in a loop and stop the thread once $machine->connect is done. Turns out that this is not so easy as well, because the threads need to share the $machine object and of course need to do properly locking. In the end I decided to use the "blindly hope that 60 seconds is enough" approach for now and come up with a better solution later. Other VM tests surely use sleep as well, but it's $machine->sleep, which is bound to the clock of the VM, so if the build machine is on high load, a $machine->sleep gets properly delayed but the timer outside the VM won't get that delay, so the test is not deterministic. Tested against the following revisions: 5e3fe39: Before the libgcrypt cleanup (a71f78a) that broke cryptsetup. 69a6848: While cryptsetup was broken (obviously the test failed). 15faa43: After cryptsetup has been switched to OpenSSL (fd588f9).
