Jonathan MatthewsFolks who know "rsync -F" because they already use it -- am I right in thinking that it adds these behaviours to a sync:- recursively look for .rsync-filter files in every directory in the copy source, including the top-level- apply the filters they each contain to the directory and subdirectories rooted at the same level that each file was found- exclude those .rsync-filter files from being copied to the destination Is that right? <a href="https://fosstodon.org/tags/rsync" class="mention hashtag" rel="nofollow noopener" target="_blank">#rsync</a> <a href="https://fosstodon.org/tags/sync" class="mention hashtag" rel="nofollow noopener" target="_blank">#sync</a> <a href="https://fosstodon.org/tags/data" class="mention hashtag" rel="nofollow noopener" target="_blank">#data</a> <a href="https://fosstodon.org/tags/sysadmin" class="mention hashtag" rel="nofollow noopener" target="_blank">#sysadmin</a> <a href="https://fosstodon.org/tags/filesystem" class="mention hashtag" rel="nofollow noopener" target="_blank">#filesystem</a> <a href="https://fosstodon.org/tags/filesystems" class="mention hashtag" rel="nofollow noopener" target="_blank">#filesystems</a>

Stefano MarinelliOne of the main criticisms I read about ZFS (mainly OpenZFS) in forums and articles is that "it's not well integrated into Linux." It's true - there is a licensing issue, and that shouldn't be underestimated. However, I believe it's wrong to judge it based on this - on FreeBSD, it is perfectly integrated (not to mention the various illumos-based OSes), and in my opinion, it should be judged for what it is, not for its integration into the different Linux distributions.<a href="https://mastodon.bsd.cafe/tags/OpenZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenZFS</a> <a href="https://mastodon.bsd.cafe/tags/ZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#ZFS</a> <a href="https://mastodon.bsd.cafe/tags/FileSystems" class="mention hashtag" rel="nofollow noopener" target="_blank">#FileSystems</a>
