[Maposmatic-dev] Possible bug: old files are kept when a city is re-rendered

[David MENTRE]

Hello,

Following a question by cworth on IRC, it appears that if we re-render
a city after the 24h time-out, new files are created but old ones are
*not* erased. This is not an issue regarding disk usage, the daemon
will remove older files. But the daemon might remove files from other
cities, rendered before, while we want to keep them.

What to you think of it:

Example of generated files:
