Subject: vserver: Don't break when no hashed files te delete.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=3dc12524a07c24998f52c2a58be15b0526326bcb;p=matthijs%2Fservers%2Fdrsnuggles.git

vserver: Don't break when no hashed files te delete.

Previously, if find would find no hashed files to delete, xargs would
still run rm without arguments. Now it doesn't.
