Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+USING UFS
+=========
+
+mount -t ufs -o ufstype=type_of_ufs device dir
+
+
+UFS OPTIONS
+===========
+
+ufstype=type_of_ufs
+ UFS is a file system widely used in different operating systems.
+ The problem are differences among implementations. Features of
+ some implementations are undocumented, so its hard to recognize
+ type of ufs automatically. That's why user must specify type of
+ ufs manually by mount option ufstype. Possible values are:
+
+ old old format of ufs
+ default value, supported as read-only
+
+ 44bsd used in FreeBSD, NetBSD, OpenBSD
+ supported as read-write
+
+ ufs2 used in FreeBSD 5.x
+ supported as read-only
+
+ 5xbsd synonym for ufs2
+
+ sun used in SunOS (Solaris)
+ supported as read-write
+
+ sunx86 used in SunOS for Intel (Solarisx86)
+ supported as read-write
+
+ hp used in HP-UX
+ supported as read-only
+
+ nextstep
+ used in NextStep
+ supported as read-only
+
+ nextstep-cd
+ used for NextStep CDROMs (block_size == 2048)
+ supported as read-only
+
+ openstep
+ used in OpenStep
+ supported as read-only
+
+
+POSSIBLE PROBLEMS
+=================
+
+There is still bug in reallocation of fragment, in file fs/ufs/balloc.c,
+line 364. But it seems working on current buffer cache configuration.
+
+
+BUG REPORTS
+===========
+
+Any ufs bug report you can send to daniel.pirkl@email.cz (do not send
+partition tables bug reports.)
