Perfect. The question that remains is, if mounting /var to a separate
partition is common enough to make RequiresMountsFor=/var the default in
brltty.service, or, if making it the default would have any unwanted
side effects. systemd makes it easy enough (as the example above
demonstrates) for a system administrator to override certain settings in
a unit. So if everything else fails, we can still document this trick
somewhere. However, I'd rather have the default brltty.service unit
DTRT whenever possible. Question is, shall we list all directories
relevant to BRLTTY in RequiresMountsFor=? Or just all the
top-level directories? Something like
RequiresMountsFor=/etc /lib /var
