What about Fedora? This system I'm on now started as Fedora 16 and has |
| 19 |
been upgraded step by step to 23. /bin, /lib, /lib64, and /sbin are |
| 20 |
symlinks but I'm pretty sure it didn't start out that way. I knew the |
| 21 |
change was coming but when it actually happened, I didn't notice for |
| 22 |
quite a while. |
