When trying to create a directory relative to the current working directory, a directory is created at the root of the filesystem instead. This patch ensures that directories specified with relative paths will be created in the current working directory. Fully qualified paths aren't affected Signed-off-by: Major Hayden <major@mhtx.net>

- If C(directory), all immediate subdirectories will be created if they

do not exist, since 1.7 they will be created with the supplied permissions.

If C(file), the file will NOT be created if it does not exist, see the M(copy)
|
|
or M(template) module if you want that behavior. If C(link), the symbolic
|
|
link will be created or changed. Use C(hard) for hardlinks. If C(absent),
|
|
directories will be recursively deleted, and files or symlinks will be unlinked.
|
|
If C(touch) (new in 1.4), an empty file will be created if the c(path) does not
|
|
exist, while an existing file or directory will receive updated file access and
|
|
modification times (similar to the way `touch` works from the command line).
