Hi all.
Crawl is not correctly working because of lack of directory permissions.
How can i correctly/safely set that permissions for saving data files of
Crawl?
Bugzilla ticket: https://bugzilla.redhat.com/show_bug.cgi?id=1458489
Affected package: https://admin.fedoraproject.org/pkgdb/package/rpms/crawl/
See: https://fedoraproject.org/wiki/SIGs/Games/Packaging
Starting at "If necessary, a game can be made setgid 'games' in order to allow a
shared scoreboard file..."
note that for games like this you will typically want to use a game
specific user and a crawl directory under /var/games, so that you
get /var/games/crawl which is owned by the group crawl and then
make the crawl binary sgid crawl. Actually if you do that you
can skip the dropping rights dance described since a rogue-ish
game like crawl properly will have multiple places where it
opens files and thus will be hard to get right wrt dropping sgid
rights.
Alternatively you could just make it access all shared files on
a per user basis putting them in $HOME/.config/crawl you can
user getenv("HOME") from C to get the users homedir, in that
case don't forget to call mkdir to create the $HOME/.config and
again for $HOME/.config/crawl (and ignore error returns since
if the dirs exist mkdir will give an error).

Hans
