Package: initramfs-tools
Version: 0.130
Severity: wishlist

Showing the user warnings like
systemd-udevd[68]: hwdb.bin does not exist, please run systemd-hwdb update
in journalctl is bad, because according to e.g.,
https://bbs.archlinux.org/viewtopic.php?id=189536
there is nothing he can do about it.

I'm sorry I don't know the exact package to assign this bug to.

Ok, let's assume it was from the initramfs then. On your real system you
should have a /lib/udev/hwdb.bin file.

The initramfs does not ship a hwdb.bin. It's not strictly needed and
would unnecessarily blow up the size of the initramfs.
Some of the udev rules shipped in the initramfs do try to run the hwdb
builtin though, like /lib/udev/rules.d/50-udev-default.rules.

Not having the hwdb.bin is not a critical error though, that's the
reason why the log message you saw is only printed if you enabled debug
logging:

src/libsystemd/sd-hwdb/sd-hwdb.c:                log_debug("hwdb.bin
does not exist, please run systemd-hwdb update");

The default log level is not debug, I'm therefor closing this bug report
as this is a local configuration issue. You basically asked for udev to
be more verbose, so this is what you get.

Regards,
Michael
