It does create an @ subvolume into which all other subvolumes are created including .snapshots. 0:install:/mnt # btrfs sub list -t /mnt/ ID gen top level path -- --- --------- ---- 257 31 5 @ 258 12 257 @/.snapshots 259 37 258 @/.snapshots/1/snapshot 260 14 257 @/boot/grub2/i386-pc 261 15 257 @/boot/grub2/x86_64-efi 262 16 257 @/opt 263 17 257 @/srv 264 18 257 @/tmp 265 19 257 @/usr/local 266 35 257 @/var/cache 267 21 257 @/var/crash 268 23 257 @/var/lib/libvirt/images 269 23 257 @/var/lib/mailman 270 25 257 @/var/lib/mariadb 271 26 257 @/var/lib/mysql 272 26 257 @/var/lib/named 273 28 257 @/var/lib/pgsql 274 35 257 @/var/log 275 29 257 @/var/opt 276 30 257 @/var/spool 277 35 257 @/var/tmp The installation time rootfs is 0:install:/mnt # mount | grep btrfs /dev/vda2 on /mnt type btrfs (rw,relatime,space_cache,subvolid=259,subvol=/@/.snapshots/1/snapshot) I don't really understand the point of this additional layer of nesting under @. I didn't test if it's still changing the default subvolume, rather than using rootflags=subvol or subvolid. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
