pawan commented on MESOS-7262:
------------------------------
Even a if check to see if the link already exists before trying to (re)create
it would suffice.
> Symlink mesos-agent to mesos-slave on `make install` not idempotent
> -------------------------------------------------------------------

> Key: MESOS-7262
> URL: https://issues.apache.org/jira/browse/MESOS-7262
> Project: Mesos
> Issue Type: Bug
> Components: cmake
> Affects Versions: 1.2.0
> Reporter: pawan
>
> I issued a make install twice after building Mesos from source, but its
> failing with the following error:
> {code}
> ln -s mesos-agent mesos-slave
> ln: failed to create symbolic link ‘mesos-slave’: File exists
> {code}
> I believe `make install` has to be idempotent. It looks like LN_S in Makefile
> aliases to `ln -s` and not `ln -snf` which would do it.
