From 43d010bd0f9e01d1652e284c77d1839a4bf16607 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Wed, 24 Feb 2021 23:30:15 -0500 Subject: Fix parsing of Tmpfs field in compat create Create is not formatted as `key=value` but rather `key:value` (technically `path:option1,option2`). As such we can't use the stringMapToArray function, and instead need to generate it manually.
