This directory never seemed to exist. The wording is very similar to
that of the Rules Files section, so it is possible that the same text
was copied and pasted by mistake. The HWDB never looked for files in
/run.
Having a non-volatile index of volatile files would probably not be
useful.
Introduce UDEV_HWDB_PATH, containing a colon-separated path with hwdb
files in it. The whole path is searched, in addition to the system
locations, when searching for hwdb files.
Due to how conf_files_list_strv is implemented, as a thin wrapper
around the internal function, it is easy to also implement a variant
accepting a search path in the same way. Since the internal function
expects an allocated array of allocated strings, the path scanning is
done in 2 steps, to first get the array length, and then duplicate the
items. It is not possible to use strtok(_r) here because it would work
for only 1 pass.
* src/shared/conf-files.c (conf_files_list_follow_path): New function.
(conf_files_list_strv_path): Use it here.
* src/shared/conf-files.h: Export the signature for the _path variant.
* src/udev/udevadm-hwdb.c (list_conf_file_path): New function
replacing conf_file_dirs.
(help): Document the search path for hwdb files.
(adm_hwdb): Use list_conf_file_path and conf_files_list_strv_path.
* man/udevadm.xml: Mention UDEV_HWDB_PATH.
* man/udev.xml: Same.
* man/udevadm.8: Regenerate.
* man/udev.7: Same.
Instead of always writing /etc/udev/hwdb.bin or UDEV_LIBEXEC_DIR
/hwdb.bin, let the user specify a full file name.
* src/udev/udevadm-hwdb.c (adm_hwdb): New option "output". Construct
hwdb_bin when processing options, and prepend root after processing
options.
* man/udev.xml: Mention --output.
* man/udevadm.xml: Document --output.
* man/udev.7: Regenerate.
* man/udevadm.8: Same.
* src/libudev/libudev-hwdb.c (get_hwdb_bin_paths): New function,
replacing hwdb_bin_paths.
(struct udev_hwdb): New bin_paths field.
(udev_hwdb_new): Initialize it with get_hwdb_bin_paths.
(udev_hwdb_validate): Use the bin_paths field to find hwdb.bin.
(udev_hwdb_unref): Free the bin_paths field.
* src/libudev/libudev.h: Warn about UDEV_HWDB_BIN.
* man/udev.xml: Mention run-time UDEV_HWDB_BIN.
* man/udev.7: Re-generate.
In the long run we really should figure out if we want to stick with 8ch
or 2ch indenting, and not continue with half-and-half. For now, just
make emacs aware of the files that use 2ch indenting.

This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.
This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.

When manpages are displayed on a terminal, <literal>s are indistinguishable
from surrounding text. Add quotes everywhere, remove duplicate quotes,
and tweak a few lists for consistent formatting.

Fixed typos, serial comma, and removed "either" as there were more
than two options. Also did an extra rename of "system-shutdown"
to "systemd-shutdown" that was forgotten in commit
8bd3b8620c
Since the binary name is now hidden away in /usr/lib/ the primary user
handle for the udev service is the unit name, hence change the man page
to be available under the unit name, and make the binary name an alias
for it.
