Nothing readily available, can I be a source? The remaining nugget/memory on this I have is a fairly open ended... "it depends [on the filesystem]". It's been a while since I dove into this earnestly. IIRC there's no single journal mechanism - they all choose to do it (or not) in their own way. Journaling was just one example, too. Let's not ignore other quirks, like how BTRFS conflates volume/filesystem management... and may exhibit behavior impossible with XFS/ext{2,3,4} [under N failure conditions] WRT soft-RAID. By not mounting it, you're avoiding the "kernel/software filter" that adds entropy to an already-rich process. Side note: you caught me in a series of edits for phrasing :D
