2015-03-03importd: automatically grow /var/lib/machines/ loopback filesystem during ↵Lennart Poettering
downloads If /var/lib/machines is mounted as btrfs loopback file system in /var/lib/machines.raw with this change we automatically grow the file system as it fills up. After each 10M we write to it during imports, we check the free disk space, and if the fill level grows beyond 66% we increase the size of the file system to 3x the fill level (thus lowering it to 33%).
2015-02-26machined: if /var/lib/machines is backed by a loop file, resize it on ↵Lennart Poettering
"machinectl set-limit" When the pool size limit is altered with "machinectl set-limit", then not only set the subvolume quota of the /var/lib/machine subvolume, but also resize the backing loop file and the btrfs file system on it dynamically.

2015-01-20import: port pull-raw to helper tools implemented for pull-tarLennart Poettering
This allows us to reuse a lot more code, and simplify pull-raw drastically.

2015-01-06journald: whenever we rotate a file, btrfs defrag itLennart Poettering
Our write pattern is quite awful for CoW file systems (btrfs...), as we keep updating file parts in the beginning of the file. This results in fragmented journal files. Hence: when rotating files, defragment them, since at that point we know that no further write accesses will be made.

2014-12-25machined: beef up machined image listing with creation/modification times of ↵Lennart Poettering
subvolumes We make use of the btrfs subvol crtime for this, and for gpt images of a manually managed xattr, if we can.
2014-12-19machined/machinectl: add logic to show list of available imagesLennart Poettering
This adds a new bus call to machined that enumerates /var/lib/container and returns all trees stored in it, distuingishing three types: - GPT disk images, which are files suffixed with ".gpt" - directory trees - btrfs subvolumes
