#183 We support triggering `record` and `replay` process by passing labels through `--snapshotter-label` when run container https://github.com/containerd/accelerated-container-image/blob/main/docs/trace-prefetch.md#example-usage @shuaichang please have a try.

@simha-db thanks for asking! 1. Is side loading compressed layer files into the cacheDir supported? Yes, but it has limitations. First, you should make sure the loaded files will not...

@simha-db background download starts 600s after container started by default, which can be set by `download.delay`. Background download is performed in a seprate thread, and on-demand load won't go through...

@simha-db overlaybd-snapshotter will not try to find and validate files. There is a global lock in overlaybd-snapshotter, which makes prepare/mount layer running in serial. Usually prepare is quite fast for...

@simha-db overlaybd-snapshotter indeed prepare snapshot directory for each image layer. snapshot directory contains some meta info for overlaybd-tcmu. when `rpull`, containerd calls overlaybd-snapshotter to prepare snapshot for each image layer...

@northtyphoon many thanks! we'll be managed to figure it out.

@maxwolffe @northtyphoon sorry to keep you waiting so long. We find bug in mkdir in extfs and fix it. Also there are problems when using sparse file in lsmt, so...

Recently, we have fixed bugs in sparse file, and made some efforts to [speed up](https://github.com/containerd/accelerated-container-image/blob/main/docs/USERSPACE_CONVERTOR.md#libext2fs) converting. @maxwolffe @northtyphoon please have a try~
