Do I need to be concerned?

[Morimando]

I just let rkhunter and chkrootkit scan my system and there were some warnings:

[19:04:29] Performing filesystem checks
[19:04:29] Info: Starting test name 'filesystem'
[19:04:29] Info: SCAN_MODE_DEV set to 'THOROUGH'

[19:04:29] Warning: Hidden directory found: /dev/.initramfs

Whereas chkrootkit informs me of the following:



Searching for suspicious files and dirs, it may take a while...
/usr/lib/xulrunner-1.9.1.7/.autoreg /usr/lib/firefox-3.5.7/.autoreg /usr/lib/pymodules/python2.6/PyQt4/uic/widget-plugins/.noinit /usr/lib/pymodules/python2.6/.path /usr/lib/jvm/java-6-sun-1.6.0.15/.systemPrefs /usr/lib/jvm/.java-6-sun.jinfo

So is there a real problem or is that normal?

Looks normal to me.
