+// given root treated as the root of the filesystem, similar to a chroot. The
+// filesystem state is evaluated through the given [VFS] interface (if nil, the
+// standard [os].* family of functions are used).
+//
+// Note that the guarantees provided by this function only apply if the path
+// components in the returned string are not modified (in other words are not
+// replaced with symlinks on the filesystem) after this function has returned.
+// Such a symlink race is necessarily out-of-scope of SecureJoinVFS.
+//
+// NOTE: Due to the above limitation, Linux users are strongly encouraged to
+// use [OpenInRoot] instead, which does safely protect against these kinds of
+// attacks. There is no way to solve this problem with SecureJoinVFS because
+// the API is fundamentally wrong (you cannot return a "safe" path string and
+// guarantee it won't be modified afterwards).
+//
+// Volume names in unsafePath are always discarded, regardless if they are
+// provided via direct input or when evaluating symlinks. Therefore:
+//
+// "C:\Temp" + "D:\path\to\file.txt" results in "C:\Temp\path\to\file.txt"
