[Merkaartor] Auto-updating merkaartor: Linux/OSX sysadmin input requested

Hi All,

I'm keen to implementing an auto-update feature in Merkaartor, which would
allow quick deployments of point releases without all the hassle of full
releases.

While doing this in Windows (where all files related to an application
reside in the same directory) seems pretty obvious, I have no clue on how
this is done in Linux/OSX, where the sys folders are supposed to be
read-only for a plain user and where package management more or less imposes
a "static" file system.
Bottom line: How does firefox auto-updates itself on these platforms?

This is about the actual files, e.g. is /usr/bin/firefox replaced in the
process or is it just a stub to the actual executable located somewhere
else?

Thanks for your feedback
