A fork of Rancher's local-path-provisioner at v0.0.36. The behaviour is unchanged and deliberately so — a directory on the node a pod lands on is the right thing for a disk. What changes is identity. The provisioner answers to hanzo.ai/volume rather than rancher.io/local-path. That is not branding: two provisioners sharing one name race for the same claims, and a stock k3s carries the upstream one, so a cluster running both would settle our storage by chance. Data lives at /var/lib/hanzo/volume, so reading a Hanzo cluster does not mean learning another vendor's directory. Apache-2.0 as published, unaltered, with Rancher's attribution in NOTICE. The README says what this is not: durability. A volume here dies with its node. That is hanzoai/replicate's question, one layer up, and keeping the two apart is what lets the disk stay this simple.

|
|
// The call that was used looked like the following:

|

// url.Parse(purell.NormalizeURL(parsed, purell.FlagsSafe|purell.FlagRemoveDuplicateSlashes))

// To explain all that was included in the call above, purell.FlagsSafe was really just the following:
|
|
// - FlagLowercaseScheme
|
|
// - FlagLowercaseHost
|
|
// - FlagRemoveDefaultPort
|
|
// - FlagRemoveDuplicateSlashes (and this was mixed in with the |)
|
|
//
|
|
// This also normalizes the URL into its urlencoded form by removing RawPath and RawFragment.
