Don't know, Looking: 8.1 /usr/src/release/scripts/make-memstick.sh man makefs -t fs-type ... The following file system types are supported: ffs BSD fast file system (default). .... FFS-specific options .... version UFS version. 1 for FFS (default), 2 for UFS2 /usr/src/release/Makefile --> scripts/doFS.sh: newfs -i ${FSINODE} -o space -m 0 /dev/r${VNDEVICE}c ... newfs -O1 -b 4096 -f 512 -i ${FSINODE} -o space -m 0 /dev/${MDDEVICE} man newfs: -O filesystem-type Use 1 to specify that a UFS1 format file system be built; use 2 to specify that a UFS2 format file system be built. The default format is UFS2. If anyone fancies looking deeper, please do :-) Cheers, Julian -- Julian Stacey, BSD Unix Linux C Sys Eng Consultants Munich http://berklix.com Mail plain text; Not quoted-printable, Not HTML, Not base 64.
