Just that it is not lost,
debian provides a facility to provide normally incompatible
binaries. (eg, different versions, different vendors)
they call it alternatives. (See /etc/alternatives)
one example: jvm. or cc.
on my server:
$ ls -l /usr/bin/cc
lrwxrwxrwx 1 root root 20 Mar 19 13:10 /usr/bin/cc -> /etc/alternatives/cc
$ ls -l /etc/alternatives/cc
lrwxrwxrwx 1 root root 12 Mar 19 13:10 /etc/alternatives/cc -> /usr/bin/gcc
and you can select:
$ upate-alternatives --list cc
/usr/bin/gcc
/usr/bin/clang
That way, we could provide different squeakvm's via this tool :)
Best
