Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Don't mix up the configuration of the running kernel and the
configuration of the kernel source tree, against which DRBD is

Please, read INSTALL in the toplevel DRBD source directory (after
first typing make there, there should be an INSTALL.html, too).
Don't overlook the note about editing the drbd_config.h.

You might succeed just doing "make oldconfig",
but most likely you *NEED* to copy in the configuration file
of the running kernel first. This might be located in
/boot/config-something ...

Note that, if you have a "preconfigured kernel headers" sort of
thing *matching your running kernel*, DRBD should compile against
that cleanly with like two minor warnings, so this is probably the
most convenient way.
