I never used docker. 

It would probably have helped me when I set up my now broken accounting 
software (odoo 9) before I knew about dolibarr and before guix had containers. 
(It broke some time ago when I upgraded arch :/ Shared libraries are a 
stability risk and pain in the long run)

According to the Swedish state I have to make sure my accounting software is 
working 7 years after the end of each year.
This is to my surprise really hard with software like odoo. I would have 
upgraded long ago would it have been straightforward by the developers 
(odooization as i call it is a problem, they make money on making odoo a fast 
changing maze that has really poor documentation, cryptic errors and no free 
upgrade scripts necessitating a whole industry of paid supporters.)
