The problem is that gzip refuses to run if it detects that a file has more than 1 link. Our existing solution (removing hardlinks, compressing the man page and recreating the hardlinks) made certain assumptions about inode order that are only given on Unix v7 like filesystems meaning it didn't work properly on 'tree-based' filesystems like BTRFS or ZFS. This patch has a different more bulletproof approach: It simply replaces all hardlinks with symlinks. This is way easier because symlinks (unlike hardlinks) can point to a file that doesn't exist, therefore we can update all links before compressing the file in an easy way.
