Hi, On GNU/Linux it has been suggested before to use 'eatmydata' - a syscall wrapper making synchronous writes asynchronous - while running debian-installer. We shouldn't need synchronous writes while installing, because if interrupted, the target isn't expected to be in a usable state anyway. It allows the installer to run somewhat faster if the time taken to commit data to disk is significant (i.e. almost anything except SSDs or ramdisk). For installs to ZFS, we could use the sync=disabled option for this. In the commit.d hook we could set that option on newly-created ZFS filesystems, then at the end of the install in the finish.d hook, reset it to the default sync=standard setting. The finish.d hook is always expected to run to get a usable system (this is when zfsutils gets installed). I suggest to measure the time taken to do test-installs with/without this tweak to see if it could be worth doing.
