[pve-devel] [PATCH pve-manager 4/8] ceph: fix edge case of wrong files being deleted on purge

[Max Carrara <m.carrara@proxmox.com>]

Having a file named e.g. "60" in your current directory will cause it
to be deleted when executind `pveceph purge`. This commit fixes that
by making the config hash differ between which values represent file
paths and which don't.
