[jira] [Commented] (MESOS-7262) Symlink mesos-agent to mesos-slave on `make install` not idempotent

["Till Toenshoff (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-7262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15932131#comment-15932131 ] 

Till Toenshoff commented on MESOS-7262:
---------------------------------------

Not sure if all of those switches are generally supported.

According to my {{ln}} macOS ln manpage:
{noformat}
COMPATIBILITY
     The -h, -i, -n and -v options are non-standard and their use in scripts is not recommended.  They are provided solely for compatibility with other ln implementations.

> 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.
