Hmm, actually you might have found a bug. # btrfs subvol list / ID 272 gen 4276 top level 5 path boot ID 273 gen 4770 top level 5 path root ID 274 gen 4680 top level 5 path home ID 275 gen 265 top level 5 path boot_ro_installed ID 276 gen 280 top level 5 path root_ro_installed ID 277 gen 280 top level 5 path home_ro_installed ID 283 gen 327 top level 5 path boot_ro_installed+updates ID 284 gen 329 top level 5 path root_ro_installed+updates ID 285 gen 329 top level 5 path home_ro_installed+updates ID 286 gen 399 top level 5 path boot_ro.3 ID 287 gen 400 top level 5 path root_ro.3 ID 288 gen 1603 top level 5 path home_ro.3 ID 473 gen 2105 top level 5 path boot_ro.2 ID 474 gen 2106 top level 5 path root_ro.2 ID 475 gen 2107 top level 5 path home_ro.2 ID 476 gen 4136 top level 5 path home/chris/Downloads/git ID 485 gen 3144 top level 5 path boot_ro.1 ID 486 gen 3145 top level 5 path root_ro.1 ID 487 gen 3146 top level 5 path home_ro.1 ID 488 gen 3880 top level 5 path home/chris/Downloads/git/kernel # btrfs subvol list / -o # btrfs subvol list /home -o # btrfs subvol list /home/chris/Downloads/ -o # btrfs subvol list /home/chris/Downloads/git -o It seems for sure that the last three should have reported ID 476 and 488. And probably the first should also have listed 272 and 274. 273 is mounted at / 272 is mounted at /boot 274 is mounted at /home man btrfs " -o print only subvolumes bellow specified <path>." Small typo while we're at it, below should have one l.
