I'd prefer of course some design documentation (I refuse to believe the UFS2 disk format was designed entirely in source code form without paper/html reference documentation) What I have is src/sys/ufs/* src/lib/libstand/ufs.c and now src/sys/boot/common/ufsread.c This is a very good start but is there really not any paper doc or design reference or even an email thread on a mailing list when people were designing UFS2? My second question (since now we can poke around perhaps) is if there is a defined way to detect a "dangerously dedicated" disk in order to support these system configurations..? -- Matt Sealey <matt@genesi-usa.com> Manager, Genesi, Developer Relations > -----Original Message----- > From: R.
