FreeBSD/src b4b3e34 (r345491) — sys/conf options, sys/fs/tmpfs tmpfs_vfsops.c tmpfs.h
Make TMPFS_PAGES_MINRESERVED a kernel option
TMPFS_PAGES_MINRESERVED controls how much memory is reserved for the system
and not used by tmpfs.
On very small memory systems, the default value may be too high and this
prevents these small memory systems from using reroot, which is required
for them to install firmware updates.
