Hi Tony,
the problem with system-wide installations is important enough to be
mentionned multiple times in the Bioconda paper just published in
Nature Methods:
"Importantly, it obviates reliance on system-wide administration
privileges by allowing users to generate isolated software
environments in which they can manage software versions by project,
without generating incompatibilities and side-effects"
"The alternatives can be categorized into system-wide (Debian-Med,
Genotoo Science, Biolinux, and Homebrew) and per-user (EasyBuild, GNU
Guix, and BioBuilds) installation mechanisms. The system-wide
approaches lack the ability to put the scientist in control of the
installed software stack, and thus do not meet the requirements for
reproducibility outlined above."
"With its ability to maintain isolated software environments,
integration into major workflow management systems, and lack of
requirement for any administration privileges for use, the Conda
package manager is the ideal tool to ensure sustainable and
reproducible software management."

In Debian we do not have native tools for making userland
compartimentalised environments, but still, it would be really nice to
be able to run install commands in the shape of:
apt install --local thispackage/thatversion
and get the version from snapshot.d.o if needed.
Have a nice day,
Charles
