How safe is it to delete usr/bin/X11 'dummy' item on Linux debian FS
I don’t think anything in the current release of Debian relies on the
/usr/bin/X11 symlink; however as a general rule, since
/usr/bin/X11 belongs to a package (
x11-common), you shouldn’t delete it manually. Everything under
/usr, apart from
/usr/local, is supposed to be managed by the package manager.
If you really want to delete it, feel free to go ahead and do so; if anything breaks as a result, re-installing
x11-common will restore the link.
