organization, there can be hundreds of user logins in a public
workstation each day, among more than one thousand of users.
Since each user login produces a 8MiB sparse log file in
/var/log/journal/xxxxx/, significant disk space is consumed.
From the administrator point of view, it is desirable to
prioritize system log over user log. For example, when total
log size exceeds SystemMaxUse, user log is vacuumed / rotated
before system log. Can we achieve this goal under current
implementation?</span><br style="color: rgb(34, 34, 34);

the size of pre-allocation (in my case, 8MiB), is probably
determined platform-wise. Here[1] I include some relevant
platform info that might aids debugging.</span><br style="color:
