It's probably not the best solution, but I borrowed tm_clone and tm_ln
from tm_nfs, and the rest of the files from tm_ssh to create my own tm
stuff, I had to modify the clone and ln files to ssh the remote hosts
instead of executing in the local system.
So far cloning seems to work fine, with contextualization and everything,
but I'm having problems with ln
[VMM][I]: error: unable to set user and group to '107:107' on
'/var/lib/one//16/images/disk.0': Invalid argument
I blame it in the security configuration of the NFS server since it doesn't
allow me to use certain groups even as root.
At least I'm on the road again.
Do not let me induce you to satisfy my curiosity, from an expectation,
that I shall gratify yours. What I may judge proper to conceal, does
not concern myself alone.
