Configuring a Bluetooth GPS receiver on Gentoo was pretty straight forward for me.
This assumes that you already have the bluetooth stack up and running on your Gentoo box.
# emerge -p gpsd
# hcitool scan
# sdptool browse 00:0B:0D:6E:65:8A
Browsing 00:0B:0D:6E:65:8A …
Service Name: SPP slave
Service Description: Bluetooth SPP V1.23

Language Base Attr List:
# rfcomm connect 0 00:0B:0D:6E:65:8A
Connected /dev/rfcomm0 to 00:0B:0D:6E:65:8A on channel 1
Press CTRL-C for hangup
On another terminal, start the gps daemon.
# gpsd /dev/rfcomm0
The fun begins:
I run into some problems when I upgraded udev to version 103 on Gentoo.
In order to have it working I needed to:
emerge -C coldplug
emerge -C hotplug
emerge -C hotplug-base
emerge -C udev
rm -rf /etc/hotplug
rm -rf /etc/hotplug.d
rm -rf /etc/udev
rc-update del coldplug
rm -f /etc/init.d/coldplug
See http://www.gentoo.org/doc/en/udev-guide.xml and http://webpages.charter.net/decibelshelp/LinuxHelp_UDEVPrimer.html
for more information about udev.
For the first time ever, the Linux Kernel includes a stackable file system. The new file system name is eCryptfs and it is based on FiST.
“eCryptfs stores cryptographic metadata in the header of each file written, so that encrypted files can be copied between hosts; the file will be decryptable with the proper key, and there is no need to keep track of any additional information aside from what is already in the encrypted file itself. ”
eCryptfs can make use of the TPM (Trusted Platform Module) using TPM Keyring.
