Hi Tobias,
The normal way to handle this would be as part of the installation 
process. A yum or apt package can make the modifications necessary by, 
for example, installing a squeakvm.conf file in the appropriate 
directory (/etc/security/limits.d on Ubuntu, other distros may vary).

This is where package maintainers can add value for a tool such as 
squeak. They can hide all the nasty config file changes that a 
particular tool may require that may freak out the uninitiated. Asking 
someone to "apt-get install squeakvm" is so much nicer than asking them 
to edit config files :) You "just" need to find someone to do the leg work.
