- use fs_cstotal.cs_nifree rather than fs->fs_ncg * fs->fs_ipg to
determine the number of free inodes available in the file system
- don't count '.' (the root node for a level) in inode sizing, since
the parent has already been counted
- some more todo items
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
mkfs() do its job
- pass cpgflg=1 to mkfs() if the user provided cpg, =0 otherwise
- improve error reporting in ffs_write_file()
- only add superblock & block map slop for one cylinder group.
trying to calculate the number of required cylinder groups caused
too many problems when tweaking parameters for small file systems.
rely upon slop from minfree, and upon ffs_write_file() to complain
if the user is too aggressive about tweaking the parameters
<ufs/ufs/inode.h>, since the latter has a lot of cruft we don't need
and it #include's way more stuff in <sys/*> (etc) than is needed here.
yet another nail in the "let's make makefs a proper host tool" coffin.
- #include <ufs/[uf]fs/*.h> instead of "ufs/[uf]fs/*.h", and don't bother
with -I../../sys; we'll solve the hostprog problem another way and
unconditionally pulling in NetBSD-current's usr/src/sys on a host system
could be a Bad Thing.
- when calculating file size, round up to frag size not block size
- #define FFS_EI in makefs.h, and include that before [uf]fs/*.h
other stuff:
- round up final size to next block (instead of next sector)
- protect makefs.h from multiple inclusion
information and a link to the appropriate fsinode, and `fsinode' contains
the inode information and a reference count. multiple fsnodes may point
to the same fsinode. this replaces the 'dup' pointer in the previous code.
It doesn't need any special privileges or kernel devices.
Only ffs image creation is supported at this time, although makefs has been
designed to allow the addition of other file system formats by writing new
back-ends.
This program was designed & implemented by Luke Mewburn of Wasabi Systems.
