make install - Text file busy

[licaon-kter]

Debian Sid 64-bit, make install:

make[1]: Entering directory '.../go/src/github.com/evilsocket/opensnitch/daemon'
cp: regular file '/usr/local/bin/opensnitchd' can't be created: Text file busy
make[1]: *** [Makefile:5: install] Error 1

I can install if I first stop the daemon, then install, then restart... which makes it a pain, so do I have to stop the networking first, right? Or directly unplug the cable? :(

[edited] yes, if you compile from the sources you have to stop and start the daemon.

$ make 
$ sudo service opensnitch stop
$ sudo cp opensnitchd /usr/local/bin/
$ sudo service opensnitch start

What happens when I stop the service exactly? Oh I know, all the programs just access the internet as they wish? That's...not what I want in a firewall. :(

if you compile from the sources

As opposed to precompiled .DEBs?

Can't that cp be replaced with whatever apt does?

[gustavo-iniguez-goya]

Well, dpkg will probably delete the target binary, and then copy the new one.

try: sudo mv opensnitchd /usr/local/bin/ and then sudo service opensnitchd restart

closing as this is something that is expected. We can help out with the doubts, but the make install is something to be used on a first installation, rather than on a regular basis.
