Amen to this. I shipped an appliance install base on Pungi/Anaconda, but in

I found SCL and got what we needed without us having to build it ourself.

My use case is for newer compilers and interpreters on development workstations.
I do not, however, manage my systems - our system administrator does that, so I
work with him to get the SCL packages installed where necessary.
I am pretty confident that if I wanted to install an SCL package and it wrapped
the system binary in some way he would refuse. He supports many more machines
than just my development group and tries to maintain the same set of packages
across all machines.
The beauty of SCL is that he can install it everywhere, but not affect anybody
that doesn't opt-in. We have a similar setup for Intel compilers, Matlab, and
other scientific software used in our organization.
So in that sense, adapting to a new approach would be troublesome, but only if
it was the only approach. As long as the system binary wrappers are in
subpackages which are optional, then I see no issues for us to continue using
future SCL packages.
Thanks,
Wes

I don't expect we'll do this for existing packages we provide, it's more a
vision for new collections (e.g. mariadb 10.2 at some point).
Anyway, do you also see the same point for those upcoming collections (where
we're not tight by keeping backward compatibility), e.g. because you're fine
with all the SCL specifics and adapting to the new way would be troublesome?

I will chime in as the "old curmudgeon" - as long as you don't break the
existing use case, then I'm fine with any changes. The blog post says subpackages will be
used to ensure no breakage - I just want to re-iterate that this is important and should
not get lost if the proposal changes.
Thanks,
Wes

Subject: [scl.org] Idea: Software Collections Daemons Made System-wide
This is basically a kick-off for getting more feedback for an idea
shared at
http://www.themindiseverything.eu/2017/03/software-collections-daemons-made.html.
Shortly, SCL has worked nicely for several years and people love them.
But even the beloved ones have some issues. And what we hear from
users, the issues with Software Collections concept currently are basically
those:
* we need to use scl enable, which changes $PATH and other environment
variables, so the binaries placed in different location are visible by
the system
* scripts originally written for "normal" MySQL use full paths (like
/usr/bin/mysql) which does not work when we only have the Software
Collection installed
* Data directory, config files and log files are on different location
than it is common
The blog post tries to summarize possible solution, which I'm looking
for feedback now, ideally by replying to this mail..
TIA,
Honza
