2015-05-05lockfile-util.[ch]: Split out from util.[ch]Colin Walters
Continuing the general trend of splitting up util.[ch]. I specifically want to reuse this code in https://github.com/GNOME/libglnx and having it split up will make future copy-pasting easier.

2015-01-19machined: refer to the disk space allocated for an image to "usage" rather ↵Lennart Poettering
than "size" After all, it's closer to the "du"-reported value than to the file sizes...
2015-01-15import: rename "gpt" disk image type to "raw"Lennart Poettering
After all, nspawn can now dissect MBR partition levels, too, hence ".gpt" appears a misnomer. Moreover, the the .raw suffix for these files is already pretty popular (the Fedora disk images use it for example), hence sounds like an OK scheme to adopt.
2015-01-14nspawn: add file system locks for controlling access to container imagesLennart Poettering
This adds three kinds of file system locks for container images: a) a file system lock next to the actual image, in a .lck file in the same directory the image is located. This lock has the benefit of usually being located on the same NFS share as the image itself, and thus allows locking container images across NFS shares. b) a file system lock in /run, named after st_dev and st_ino of the root of the image. This lock has the advantage that it is unique even if the same image is bind mounted to two different places at the same time, as the ino/dev stays constant for them. c) a file system lock that is only taken when a new disk image is about to be created, that ensures that checking whether the name is already used across the search path, and actually placing the image is not interrupted by other code taking the name. a + b are read-write locks. When a container is booted in read-only mode a read lock is taken, otherwise a write lock. Lock b is always taken after a, to avoid ABBA problems. Lock c is mostly relevant when renaming or cloning images.
