Dear all,

if i run rear on host with KVM this obove message appear.

Workaround

306        # BugError "Unexpected operational state '$state' for '$network_interface'."
307         echo "Unexpected operational state '$state' for '$network_interface'."

This is a duplicate of
#1701
which is meanwhile fixed via some commits
in current ReaR GitHub upstream master code.

FYI:
How you could use the current ReaR GitHub master code:

Basically "git clone" it into a separated directory and then
configure and run ReaR from within that directory like:

# git clone https://github.com/rear/rear.git

# mv rear rear.github.master

# cd rear.github.master

# vi etc/rear/local.conf

# usr/sbin/rear -D mkbackup

Note the relative paths "etc/rear/" and "usr/sbin/".

@slowguitar If you could confirm that with the latest git version it works that would be nice? Thank you.
