We will be using the mechanics also for ZFS systems booting with BIOS legacy boot, and the tool is used also in PMG and PBS. A symlink is kept in place for compatibility reasons The hook scripts are marked as conffiles (as all files in /etc) and are handled by dpkg-maintscript-helper(1) via dh_installdeb(1) Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com>
