[pve-devel] [PATCH v2 storage docs] Allow overrides for default directories

[Wolfgang Bumiller]

Actually, I just realized that these are actually *relative* paths
written "as absolute" paths, and if not, the error will now actually say
that it is not an absolute path as well.

Also the docs say absolute paths, but they are not.

So please add a followup which drops the use of `verify_path` (rather,
just allow all values or perhaps forbid it containing '..' (without even
bothering checking for slashes around).
