.\" Was kernel 2.0 started from a branch of 1.2.10?
.\" At least from the timestamps of the tarballs of
.\" of 1.2.10 and 1.3.0, that's how it looks, but in
.\" fact the diff doesn't seem very clear, the
.\" 1.3.0 .tar.bz is much bigger (2.0 MB) than the
.\" 1.2.10 .tar.bz2 (1.8 MB), and AEB points out the
.\" timestamps of some files in 1.3.0 seem to be older
.\" than those in 1.2.10.  All of this suggests
.\" that there might not have been a clean branch point.
