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.

I somehow dislike the wording in the man page, e.g. I will merge and fix that afterwards. |

Dear eudev developers,
In Guix, every package is installed in a separate "/usr" prefix. For instance, eudev is installed in "/usr-a/" and upower in "/usr-b/" (except it’s actually "/gnu/store/xxx-eudev-version" and "/gnu/store/yyy-upower-version", whatever). If I want to compile the hwdb database and write it to "/usr-b/lib/udev/hwdb.bin" (with "--usr"), the "--root" argument is insufficient. If I compile with --root=/usr-b, I will end up with "/usr-b/usr-a/lib/udev/hwdb.bin".
I think it would be better to let udevadm hwdb write to an arbitrary file.
What do you think?
Best regards,
Vivien
