 I was thinking of a brute force approach where it just kept creating
 copies (and using up disk space), until it found one where at least
 one block was above a specified limit (or potentially all blocks below
 a limit), at which point all files except that one could be deleted.
 The code to check which blocks are in use for each file should be
 already available in installboot :)
 
 It would not be intended for this to be default behaviour, but would
 probably make sense to build in
 - work in a temporary subdirectory so easier to cleanup
 - add optional max number of copies to try before aborting
 - add min free space in filesystem before aborting
