fix(filesystem.go): also delete group directory #231

Closed vdice closed 4 years ago

vdice commented 4 years ago

Adds logic to remove the parent (group) directory if the item being deleted is the last one in that dir

Previously, group directories -- where a group is a named (ULID or installation name) directory under the item type directories of claims, results or outputs -- would linger after deleting an installation.

@radu-matei do you think you'd have a spare moment to check this PR out?
