# Git versions before 1.7.7-2 kept about 100 hard links to
# /usr/lib/git-core/git at /usr/lib/git-core/git-* to avoid
# wasting time resolving a symlink when old scripts call "git
# foo" as git-foo. Btrfs doesn't like to have more than 130 or
# so links to a single inode in a given directory. dpkg versions
# 1.16.1 and later temporarily double the number of hard links to
# an inode when upgrading a package.
#
# Replace the hard links with symlinks _before_ upgrading to
# avoid trouble.
#
# For added fun, coreutils mv will not replace a file by a
# symlink to the same inode (bug #654666). We give
# /usr/lib/git-core/git its own inode to work around that.
