Source: apt Version: Severity: wishlist Hi,
I run eatmydata apt ... frequently and it is used widely by others when there is no need to fsync()-s during package installations or removals, but it is nice to save time and wear off SSDs later. Using fsync() is unlikely to bring any benefit when a system is very unlikely to crash or it is cheap to recreate in case of an installation failure like it is the case for provisioning containers. Also using fsync is fairly pointless when apt-btrfs-snapshot is installed and a snapshot is taken after the apt operation anyway. Ideally dpkg would provide a command line option for skipping fsync, but it is not yet the case: #923423. On APT's side I'd like to propose a config option which when set would prefix dpkg calls with eatmydata until dpkg has a better interface for disabling fsyncs. apt-btrfs-snapshot and similar tools could ship a config file snippet setting the option, Cheers, Balint -- Balint Reczey Ubuntu & Debian Developer
