I wonder whether @alas has any opinions about XFS? I remember seeing it in the Gentoo handbook and wondering what the point is if there already is ext4... (We might've talked about this before? Sorry, my memory really is bad)
@vaporeon_ copy on write and data deduplication are useful fur portage, and XFS is old enough that Gentoo thinks it a safe and reliable choice fur getting those features
@alas @vaporeon_ not sure
@vaporeon_ @aescling i did some digging, appears to be reflink style which is great at the level of individual files but can't go up to the directory/filesystem level atomically the way something like zfs snapshots can
