In early linux dayes the one sas implemented on top of the other, but
they are too different to be compatible, so that gave problems.
fcntl locks
- associated with the process id and can therefore not be
inherited by a child process.
- if a locked file is opened multiple times by a program
the first close will release all locks even if the lock
was set using one of the other fds.
flock locks
- only locks entire files.
- assiciated with an open file fd and can thus be inherited by
a child process.
There might be other differencess as well.
Don't know about linux, but some NFS implementations of file
locking was, mildly said, unreliable.

What are the permissions on /dev/sda ?
To clear a partition-table, you could also use dd:
dd if=/dev/zero of=/dev/sda bs=1 count=66 seek=446

Hi all,

Is there a command for this?
Where is the information stored?
Just like we use 'uname -a' or -s or -n for other info,
I would like to get 'Dist name/ver'.

DVD viewing is still in beta stage in both systems. There exists several
programs to do that, some more or less work under FreeBSD, for example
xine in the ports. You need to obtain a plugin for decoding the dvd
in some obscure corner of the web.

Subject: Unmangle UMSDOS Filenames
Date: Fri, 1 Jun 2001 01:06:03 -0700
I have a laptop that has a 120MB hard drive. I want to install ZipSlack
onto it, to an ext2fs partition. I used tomsrtbt to partition the drive,
and unzip the zip files (the split version on floppies). The problem is,
all the files are mangled for UMSDOS.
It seems to me, there should be a utility to take the "--linux-.---" file in
a directory, and unmangle (and fix symlinks and devnodes) all the files in
that directory. It would also be nice if that could be done recursively to
directories. Does something like this exist? If not, I think it should. I
mean, all the code to unmangle stuff must be there already somewhere. I
took a look at the kernel source for UMSDOS, and I'm not a good enough
programmer to figure out how to do that kind of stuff.
If there isn't some way to unmangle everything, how can I get ZipSlack
installed onto an ext2fs partition on my laptop? I can't think of any way
to extract the stuff to a real UMSDOS partition and then copy it to an
ext2fs partition, since there's not enough hard drive space. I can't take
the hard drive out and put it in another computer and do it, because it's a
laptop. I don't want to use UMSDOS because I'm not going to be using DOS or
Windows, and the laptop is already slow to begin with, I don't want the
overhead of UMSDOS dragging it down too. There must be some simple way
that's just eluding me.
Thanks,
Riley

If you install the current XFree86-4 port and the xine-port, then
you should be able to watch DVDs.
See

If you're up to it you can build your own system from scratch.
http://www.linuxfromscratch.org will show you how. That way you know exactly
what is installed on your sytem (you've compiled it yourself).
Only downside is, you can't install additional software via RPM. Which is
not so bad, you find the .tar.gz file and compile that as well.

John, you're awfully nice to respond in such detail to my essentially
newbie apt questions. My experiences with it have been discouraging,
and I hope to get it right this time.
With your advice (and possibly further answers to my responses below) I
hope to get a Progeny install upgraded to woody and Gnome 1.2.

I don't have the file terribly handy, but the original file had lines
like:
deb http://http.us.debian.org/debian stable main contrib non-free
and all I did was to replace "stable" with "testing" or with "woody".

Is Gnome part of woody? If so, then shouldn't "apt-get upgrade" with
"woody" in the "deb ..." lines get it? Try this question: If my
sources.list file has "deb ... stable ...", then I suppose "apt-get
upgrade" will fetch "testing". If my sources.list file has "deb ...
testing ...", then what version would "apt-get upgrade" attempt to get?
My first attempt at fetching woody was the first example, and I got the
50 MB or so changes. With the same sources.list (the one with
"testing") I went for "apt-get dist-upgrade" and didn't see what I
thought I should -- even a reboot had debian_version == potato.
What magic thing will tell me I have woody, as opposed to a broken
upgrade?

This is my prior comment again...do these lines attempt to upgrade
"testing" to "unstable"?

When the upgrade is done, should I expect to be able to search my file
system and find these files named task-* ?

Are you just being theoretical? I'm not sure how big the .com zone file
is; last time I heard, it was a big less than 2GB.
Anyway, I answered your question: upgrade libc, recompile things that
give you trouble, and be prepared for lots of things to break (or at
least fail to work for large files) anyway.

No, because in this case `faking root' means `faking the root
filesystem' (i.e., / )rather than `faking the root user'. In other
words, rpm --prefix=/some/directory means that files that would
normally be installed in, say, /usr/bin will go in
/some/directory/usr/bin instead. You won't be permitted to overwrite
any files to which you don't have access, and if the RPM file runs a
script as part of the installation process then any parts of this
script that requires root privileges will fail.
There are programs that do fake being the root user (described as
`SUID root'), and the capabilities of these programs have to be
carefully controlled in order to avoid the kind of problem you hint
at. Only the root user can make SUID root programs.
