No.

Because leaving the original lock file there caused "bundle install
--path vendor/bundle" to fail with:

I can't remember what version of Ruby it was - it was from earlier than
2015 . . it was running on whatever version of Ruby that was in the
container - which is gone because the whole docker setup was corrupted .
. I may have backups on old hard disks but it would take too long to try
and re-create old OS environment, Docker version etc so I thought the
best thing to do was just the Rails app running directly on my current
machine (Linux Fedora 31).

Thanks,

Phil.
