/usr/X11R6 sym link

[Matthias Apitz]

Hello,

I wanted to update one of my laptops with my usual procedure:

- boot from a well prepared USB key with 11-CURRENT, packages, src, ...
- wipe out with newfs(8) all file systems, but not /usr
- mount the (old) /usr as /mnt/usr
- rm -rf everything in /mnt/usr, but not /mnt/usr/home
- install 'make installworld ...' into /mnt
- ...

A pity that I overlooked that the old /usr/X11R6 was a sym link to
(fully qualified) /usr/local:

$ ls -l /mnt/usr
total 58
lrwxr-xr-x   1 root  wheel     10  7 abr  2011 X11R6 -> /usr/local
drwxr-xr-x   2 root  wheel   7680  1 ago  2012 bin
drwxr-xr-x   2 root  wheel    512 12 abr  2011 compat
drwxr-xr-x   2 root  wheel    512 18 abr  2011 games
...

This (rm -rf /mnt/usr/X11R6) damaged the system I was sitting on, i.e.
the USB key :-(

Ofc, I have had an image of the key and could recreate the key in a few
minutes. And of course, I could have seen this and ofc I will keep my
eyes wider open next time, but I'm curious: what piece of old package
could have created such a symlink in this older (9-CURRENT)
system?

Any idea?
