struct lfs.
sovs@diku.dk:
The pad2 field in struct lfs is a kludge. You
need it because the raw devices has to be written in DEV_BSIZE. The
lfs_maxsymlinklen is needed because the tells the UFS code that we
want to use 4.4BSD directory layout insted of FreeBSD 1.1.5.

buffering scheme and make it more in tune with FreeBSD's vfs_bio
implementation. The filesystem seems fairly stable, but I wouldn't recommend
it to anyone not willing to experience problems. This is very green code and
has the limitation that YOU CAN ONLY HAVE ONE LFS PARTITION MOUNTED AT A TIME.
What LFS is good for:
Non fsynced writes FASTER THAN FFS
Large deletions Increadibly fast
Reads are a little bit slower than FFS right now, but that is a factor of
how under optimized this code is. LFS should in theory perform at least as
well as FFS under fsync (iozone) type loads, and this is what I'm currently
working on.

MASTER_SITE_OVERRIDE - If set in the environment, will override everyone's

MASTER_SITE_FREEBSD - Sets OVERRIDE to be FreeBSD's own master repository.

This fixes the problem with parse errors in header files when compiling C++

Recompiling libg++ also solves the undefined synbols problem.
be callable _after_ installation in 2.1's system admin tools. This is
almost totally revamped now.
2. Support installation from DOS partition or floppy.
3. Many stray bogons eliminated. Perhaps a few introduced. One more
rev should fix this up, once I've spammed my test machine a couple of
times.
4. Installation from CD now *really* possible.
5. Allow user to specify arbitary subdirectories for NFS mountpoints -
UFS, NFS and CD distributions now share many common elements.

Don't clobber the last page of memory (where the message buffer is). Some

Remove bogus declaration of Debugger(). Call Debugger() even if DDB is
not defined, but still call panic() after Debugger() returns, although
most other SCSI drivers just call Debugger().
printf() is inconsistent with the prototype for the library printf() and
gets declared if DIAGNOSTIC is defined because <vm/vm_page.h> includes
<sys/systm.h>.
Notice that the libgcc DOESN'T change number, because there are no
changes.
Also now the gnu2bmake stuff is synchronized again.
I commit this so that others can test too.
You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.
Thanks to Bruce for rounding up our changes to gcc.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.
