The following reply was made to PR misc/4576; it has been noted by GNATS.

This is a ``bug'' in the default /etc/login.conf settings. The resource limits for 'daemon' are what /etc/rc (and hence the mfs mount at boot) are run with. 'daemon' has a datasize limit of 32MB, and mount_mfs goes to a fair bit of trouble to fit within it's hard data limit. I have been thinking of having mount_mfs reset it's hard data limit to infinity if run by root (such as at boot time). This will get a fssize of what was asked for in spite of the /etc/login.conf settings. Another fix would be to put some more suitable settings for daemon in login.conf. Cheers, -Peter
