It is after all built on a database No, it's not. It's just easy to build a database on top of, without having to redesign the storage system. As I said in my last message, go read the whitepaper. How can there be a claim that Reiser4 is ready to be merged into the Kernel without ACL support? Because things don't have to have every feature imaginable to be merged. In fact, quite the opposite -- they have to be sane and stable.

ACLs finally restored some of this power although the implementation in Linux is crude at best. That's why the "standard" way isn't happening. Although I wish they'd left it in, and the standard xattrs interface, and created the "better" interface later. I thought there is a glimmer of hope that some day Linux will catch up to where Novell was 15 years ago. It is so frustrating dealing with Linux culture and VI mentality trying to get people to think outside the box. Speak for yourself. After all, you wanted us to do the "standard". Better yet, go read the whitepaper. It's on the homepage at namesys.com, and it's very human-readable.

A minor nitpick: if you wish to delete a file, you need write permission on the directory - the permission on the file doesn't really matter (unless the sticky bit set is set on the directory, in which case you have to own the file to delete it...). > ACLs finally restored some of this power although the implementation in > Linux is crude at best.

You might be interested in the Linux Trustees project: http://trustees.sourceforge.net/ Still not not the match of NetWare's flexibility, but it's a step in the right direction. If it patches correctly into a -mm kernel, I think it should even work on top of reiser4. Additionally, Novell has released Open Enterprise Server, which supposedly supports creation of NSS volumes on Linux (SUSE Linux Enterprise Server 9), supporting trustees! -- Matt Stegman
bad blocks on disk. Which files are damaged?
Hello all... I have a harddisk here which developed bad blocks. It is quite large and only a few blocks seem to be affected. I ran several scans wirh the "badblocks" tool and got a map of defective blocks out of this. Now I'd really like to find out which files on the Reiser3.6 FS on the defective disk are probably damaged. Is there a way or maybe even a HowTo to tell this without huge effort? Maybe even some kind of script or tool? best regards, Fionn -- I believe we have been called by history to lead the world. G.W. Bush, 2002-03-01

It's not in 2.6.13-rc6, and I doubt Linus is going to blop *that* big a chunk of code in this late - it's already well into the "is this 3-liner too drastic" phase. What happens when the 2.6.14 tree opens is up to Linus and Andrew. pgpvushrPVW5F.pgp Description: PGP signature

And you *could* ask, I suppose, why there are no compression or other plugins available in a system based on plugins. Why there is no repacker when there is supposed to be an interface for one and is one of the main reasons Reiser4 is so wonderful. Why... The reason? Time. Money. Resources. And indeed, the bare bones of Resier4 (the only part the -mm team wanted) are ready for vanilla inclusion. The problem is we can't go any further until this is done -- otherwise, a huge bug that crops up could end up going undetected for a long time, and fixing it could end up being a huge task that could take ages. Reiser4 is undertested and underfunded. Vanilla could change that. Note, this is all speculation. -- ~Mike - Just my two cents - No man is an island, and no man is unable.

EXT3 has ACL support. Every other file system has ACL support. How can there be a claim that Reiser4 is ready to be merged into the Kernel without ACL support? Here I am gearing up to switch over and now I can't. I just spent the last few week hassling Redhat to make Fedora more Reiser friendly. This is moe than just a little disapointing.

Re: reiser4progs 1.0.5 configure script and libaal 1.0.5
Hello The lastest reiser4progs (1.0.5) can't find libaal in configure script. More precisely it doesn't find libaal because of version problem Maybe it is a permission problem caused by SELinux. I had similar troubles myself. Disabling SELinux in /etc/selinux/config helped. Take a look at /var/log/messages if there are any SELinux related access-denied messages. On my system it seemed that ldconfig was not able to generate symbolic links for libaal and therefore reiser4progs were not able to find the required libaal version. Here are two mailing list entries dealing with ldconfig/SELinux problems: http://lists.freshrpms.net/pipermail/freshrpms-list/2004-December/011960.html https://www.redhat.com/archives/fedora-test-list/2004-December/msg00275.html Best regards, Peter.
