Free list in SCO file system

[Thomas]

help! i need info about the sco xenix file system for 286's and 386's.
the info an the man page for 'filesystem' seems to be wrong. what i would
like to know is:

how is the free list stored?

in /usr/include/sys/filsys.h struct filsys is defined. it is the format of
the superblock. in the struct, the array s_free[] holds the first NICFREE
free block numbers. in unix, s_free[0] is the link to a chain of indirect
blocks containing some more free block numbers. unfortunately, this is *not*
the way it works in xenix *86.
the man page for 'filesystem' is the same as on a vanilla sys v system. i guess
sco forgot to document their "enhancements" there.

does anyone know? sco?
