Hi Ralf (again!)

Doing a quick test.. no guts/no glory..

sshpass -p 'big_foo' scp -r  root@1x.3x.5.1:/ /

so I'm on the "local" box and copying from the 1x.3x.5.1 box  to the
local dir/tree

i'm getting
scp: read remote
"/sys/kernel/tracing/events/sched/sched_process_wait/inject" : Failure
scp: Download of file
/sys/kernel/tracing/events/sched/sched_process_wait/inject to
//sys/kernel/tracing/events/sched/sched_process_wait/inject failed

now, the local box also has this file.. when I did a quick ls -al foo

I get things like..
scp: remote open "/sys/kernel/security/integrity/ima/policy": Permission denied
scp: Download of file /sys/kernel/security/integrity/ima/policy to
.//sys/kernel/security/integrity/ima/policy failed
scp: download "/sys/kernel/security/apparmor/.null": not a regular file
scp: download /sys/kernel/security/apparmor/policy: not a regular file

Out of curiosity, I also dir a
root@1x.3x.5.1:/ .    instead of
root@1x.3x.5.1:/ /

to see if anything really changes.. doesn't appear to change much...
 "//"   ".//"
I'm assuming that "/sys" files are "protected"...

I'm letting this run to get to the "/etc"   "/var/www"  to see what happens..

This is all due to digitalocean appearing to have an issue with
duplicating/cloning an instance to another instance using their
website/platform.

thoughts?
