The answer below describes how to mount a BitLocker partition under Linux without using dislocker. Instead, it uses cryptsetup and achieves full auto-mount capability. For security, the partition where /etc/cryptsetyp-keys.d lives should itself be encrypted at rest. In my setup, this is the case as the root partition is LUKS-encrypted, with the unlocking occurring during boot via a passphrase.

Fixing NTP Refusing to Sync Article from Petr Baudiš () under Creative Commons Attribution-ShareAlike 3.0 Unported License. April 26th, 2010 I have just been confronted by NTP absolutely refusing to touch my system’s clock. The trouble with NTP is that it is absolute PITA to debug it at all since when it does not get in sync with its peers, it goes at great lengths to make its reasons as incomprehensible as possible.
