checking the content dirs for clashes via abs_path must be done after the logic for creating them ran, as abs_path is working on actual filesystem level, so it will return undf if the directory does not exist, in which case we then set a hash entry for "undef", and the next for loop round then resolved again to "undef", resulting in a false-positive of the check. Avoid the dangerous "return if" stanzas and reverse them to an actual if block, which is much safer to adapt. Then move the check for duplicate content-dir usage after that. best viewed with white space change ignored: git show -w Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
