The section of the manual describing the makedev syntax is not
up-to-date with the current features, and does not properly describe
existing ones.
- extend the list of types with the requirements on the existence of
the target file or directory; for 'c', 'b', and 'p', the existence
requirement is inherited from mknod(2):
ERRORS
...
ENOENT A directory component in pathname does not exist or is a
dangling symbolic link.
for the other types, the existence requirements are extracted from
the source of makedev.c;
- format the types flags, so they are rendered in monospace;
- extend the 'mode' description, as it can be set to -1 for 'f', 'd',
or 'r', so that only the uid and gid are set. This is most useful
for 'r', where setting the same mode recursively for all the
sub-directories and files alike does not really make sense; indeed
in this case, the modes are usually set correctly when the package
(or rootfs overlay) installs the files, and only the uid and gid are
interesting to set;
- extend and update the examples to show-case the -1 mode use-case.
