Hi Helmut,
This was my fault as I prepped most of the package changes for this
Luanti rename. I applied your patch [0] and don't see any diverted files
after upgrading from minetest-server 5.8 to luanti-server on a Trixie VM:
$ ls -alh /lib/systemd/system/{luanti,minetest}*
-rw-r--r-- 1 root root 604 Feb 14 12:15
/lib/systemd/system/luanti-server.service
-rw-r--r-- 1 root root 593 Feb 14 12:15
/lib/systemd/system/luanti-server@.service
lrwxrwxrwx 1 root root 21 Feb 14 12:15
/lib/systemd/system/minetest-server.service -> luanti-server.service
lrwxrwxrwx 1 root root 22 Feb 14 12:15
/lib/systemd/system/minetest-server@.service -> luanti-server@.service
However, I observe the same results (no file loss) without the patch so
I'm unsure exactly how to reproduce the conditions under which file loss
will occur. I saw case1.sh under DEP17 uses dpkg directly whereas I used
apt so maybe some magic is happening I don't yet understand.
Cheers,
Travis
