After Ring the various FMs including, but not limited to, mdmfs(8), mdconfig(8) malloc(9), I am unclear whether of not the memory used by md of type MD_MALLOC is kernel memory which will not be swapped, or not. On the same subject, does the the MD_SWAP backed device simply use swapable userland VM or does it specifically use a piece of the (presumably) disk backed swap partition? FYI, the relevant fstab entries for a malloc backed disk having a UFS2 with softupdates and async would look like: md /tmp mfs rw,-M,-s128m,async 2 0 md /var/run mfs rw,-M,-s1m,async 2 0 -Andrew- -- _______________________________________________________________________ | -Andrew J.
