Someone at my org was experimenting with repositories and links on the cobbler server, like:

# ls -ld /var/www/cobbler/repo*
lrwxrwxrwx.  1 root root      34 Mar 19 11:26 repo_mirror -> /var/www/cobbler/repo_mirror_build/
drwxr-xr-x.  2 root apache  4096 Mar 19 20:07 repo_mirror_build/
drwxr-xr-x.  2 root apache  4096 Mar 19 20:08 repo_mirror_patch/
Unfortunately when I ran a "cobbler sync" it deleted both "real" directories:
# cobbler sync
task started: 2014-03-19_200751_sync
task started (id=Sync, time=Wed Mar 19 20:07:51 2014)
running pre-sync triggers
cleaning trees
removing: /var/www/cobbler/repo_mirror_build
removing: /var/www/cobbler/repo_mirror_patch
So of course I'm restoring things -- but in the future, could there perhaps be a setting that prevents disastrous removal of entire repositories?  Or at the very least, a "README" or something in the directory that says "DON'T PUT USER DIRECTORIES HERE" or something?
