Hi Brenda,
Long question, long answers:
Question 1.
CAELinux is a normal Ubuntu distribution 8.04 produced by remastering a liveDVD with the "magic" Remastersys tool.. there is nothing really particular on the side of the OS and thus it behaves like any other Ubuntu installation.
The only limitation is that the user customization is not taken into account during install, but you can add / modify users after install.
Did you try to create a new account after installation?? Probably not, so here is the procedure:
- install caelinux,
- login as "caelinux",
- in administration menu => manage users/groups
- create a new user .. named "MarkShuttleworth" if you want
and change the default "caelinux" password to something a bit less obvious!
- login as "MarkShuttleworth" (or any other "better choice") and that's it!
I have spent some time writing scripts and customizing .bashrc to reconfigure & run properly all apps for all users... if this is not the case, you discovered a bug and it would be nice to report it!
I hope that it will convince you that CAELinux is a just like any other distribution.
Question 2:
yes, ready to install packages is the way to go... but it already exist in the form of Salome-Meca (tar.gz) and OpenFOAM binaries. These packages are made distribution independent (not .deb or .rpm) to save time and efforts: developing a package for such complex codes requires a lot of efforts and installing such codes is not a simple "copy and link" task. For example, Code-Aster is a client / server application that requires either an SSH server with "no password" authentication or RSH (not good for security !!). Copying Aster binaries would not be difficult, but automating all the "fine tuning" of the installation would be more tricky. To achieve a resonable integration of all codes in CAELinux, I had to carefully change the environment and create specific scripts to ensure that each app uses the right library versions / configuration parameter and so on. Controlling things at this level of detail is difficult to achieve in .deb packages, at least, with my little experience of it.
But YES, I agree, in the future, this would be the ideal case... just need to have enough time and find technical solution to do it!!
By the way, if anybody here has a strong experience in Ubuntu/Debian packaging... I would really appreciate some help !
