# The daily gaming budget enforces its cutoff by bind-mounting a refusal stub
|
|
# over /usr/bin/steam and the other launcher entry points. Any of those
|
|
# directives gives this service a private mount namespace, so those mounts stay
|
|
# invisible to the rest of the system: the launchers keep working while the
|
|
# counter keeps running, and the block silently becomes a no-op. That failure
|
|
# mode is invisible from the outside, which is why it is spelled out here.
|
|
# _playtime_block.mounts_are_visible() logs an error if it ever happens.
