I'm puzzled. Coming from a Tru64/TruCluster background I know CDSL's
well, but have never used bind mounts. From reading about them it
looks to me like:
a CDSL = [one] file that points to [many] files, but
a bind mount = [many] mount points that originate from [one]
Not only is the one to many relationship of a bind mount the opposite
of a CDSL, but it's not possible to replace [for example] a CDSL
like /etc/application.conf by mounting something on top of it.
How is this supposed to work?
Rgds,
