rc.sysinit calls quotacheck with parameters "-v /" for root filesystem and "-v -R -a" for other filesystems. quotacheck invoked this way will not update quota.group files. In case of root filesystem quotacheck is also invoked on read-only filesystem and doesn't have a chance to write to quota.user anyway (this has already been reported as #703 and was supposed to be fixed in initscripts 3.83 but initscripts in RawHide distribution, ver 3.92-2 still contains this bug).
quotacheck is supposed to run on the raw device, not on the mounted filesystem.
That's OK, but it still doesn't update quota.group file at least for root filesystem.
Fixed in initscripts-4.10.
