/dev/.udev? Googled, nothing. Searched here, nothing.

Running "rkhunter" brought my attention to this file -
/dev/.udev
/..
/db
/failed

Contents of /db;
block@hda
block@hda@hda1
block@hda@hda10

etc...

Doesn't matter at this point what is in /failed..

Deleting the file /dev/.udev prevents certain programs from running, including "system-config-services"...

Is this a "fake" file setup used by an intruder bypassing /var/run/udev?

If you are trying to know more about /dev/.udev, guess you should probably look into the udev source code ! Cheers !!

Most likely not, "man udev" for info and if you "grep udev rkhunter.conf" you'll see it's a common dir that can be excluded from scan.

Most likely not? A pretty equivocal response. There is no reference to /dev/.udev anywhere in the man file, only /dev and /etc/udev/. Looking into the source code is not something I have the skill or knowledge to do.

Is /dev/.udev present in others Fedora Core 5 installs?

Udev-102.tar.gz, RELEASE-NOTES, line 315:
The option "udev_db" does no longer exist. All udev state will be in /$udev_root/.udev/ now, there is no longer an option to set this to anything else. If the init script or something else used this value, just depend on this hardcoded path. But remember _all_content_ of this directory is still private to udev and can change at any time.
So this is the dir where Udev tools keep state.

In older versions of udev, you could set the location of the udev database inside udev.conf (you could set the variable udev_db just like udev_root or udev_rules). If you read the RELEASE-NOTES (specifically lines 315-316), it says there is no longer an option to alter this variable (it will always be set to “/$udev_root/.udev/”) (ever since version 076).
