Backports of patch from systemd git to stable distributions
a8040b6d0a
Fixes #10526. Even if we waited for the root device to appear, the mount could still fail if we didn't wait for udev to initalize the device. In particular, the /dev/block/n:m path used to mount the device is created by udev, and nspawn would sometimes win the race and the mount would fail with -ENOENT. The same wait is done for partitions, since if we try to mount them, the same considerations apply. Note: I first implemented a version which just does a loop (with a short wait). In that approach, udev takes on average ~800 µs to initialize the loopback device. The approach where we set up a monitor and avoid the loop is a bit nicer. There doesn't seem to be a significant difference in speed. With 1000 invocations of 'systemd-nspawn -i image.squashfs echo': loop (previous approach): real 4m52.625s user 0m37.094s sys 2m14.705s monitor (this patch): real 4m50.791s user 0m36.619s sys 2m14.039s |
