LINC-Switch build fails on NFS (or other) file system without setuid/setcap permission

It appears that during the build the following command is run:
sudo setcap cap_net_admin=ep ./rel/linc/erts-5.10.4/bin/beam.smp
Most NFS mounts (along with other shared file system mounts) don't permit setuid/setcap to be set on executables (this is a recommended best practice for configuration), so this command, and the make
, fails with a confusing error message:
==> rel (generate)
Failed to set capabilities on file `./rel/linc/erts-5.10.4/bin/beam.smp' (Invalid argument)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file
make: *** [rel] Error 1
It would be better if the build would actually complete and if you could either a) install the switch in a place like /usr/local/bin
or /usr/bin
, which are more likely to permit setuid, or b) if setuid/setcap fails, that the switch could be invoked using sudo
if necessary
