rightmost one and going left. In the above example lower1 will be the
top, lower2 the middle and lower3 the bottom layer.
+Note: directory names containing colons can be provided as lower layer by
+escaping the colons with a single backslash. For example:
+
+ mount -t overlay overlay -olowerdir=/a\:lower\:\:dir /merged
+
+Since kernel version v6.5, directory names containing colons can also
+be provided as lower layer using the fsconfig syscall from new mount api:
+
+ fsconfig(fs_fd, FSCONFIG_SET_STRING, "lowerdir", "/a:lower::dir", 0);
+
+In the latter case, colons in lower layer directory names will be escaped
+as an octal characters (\072) when displayed in /proc/self/mountinfo.
