Re: [webmin-l] Problem installing perl modules

[Jamie C. <jca...@we...>]

Hi Doug,

The problem here is that RPM extracts the post-install scripts from the package
to files under /var/tmp, and then tries to execute them. However, this isn't going
to work on your system if /tmp is mounted noexec :-(

Since it is RPM that chooses this path and not Webmin, there isn't much that
the Webmin package can do about it..
