ReiserFS is supposed to be pretty stable now, since 2.4.4, I don't think any
fixes for it went into the latest 2.4.5 kernel release.  The SuSE distro has
been including Reiser for at least a year now, and by all accounts users are
happy with it.

So what are the reasons for not using ReiserFS?  I read somewhere that even
the latest verson of lilo is starting to support booting from a reiserfs
partition.

I understand Ed's minimalist approach to using a firewall, but then you
would argue against using Debian, and applying a Linux router project, some
of which do not require a hard disk.  Better still boot from CD-ROM and use
read-only filesystems, TMPFS or RAMFS.

So does ReiserFS interact fiendishly with the network stack?  It seems a bit
implausible to me, does Ed know something in particular or is the strident
advice based on the file systems relatively new status to the standard
kernel?

BTW  A Caveat Applies

ReiserFS transaction log only applies to filesystem meta data, the journal
filesystems are not flushing data blocks any quicker than ext2, so improper
shutdowns can result in corrupt files, or loss of data, just not totally
corrupt filesystems.

I've been playing with Reiser and it's great not waiting for fsck-ing fsck.
I'm definitely going to employ it, and most of the reviews and comparisons
have shown Reiser and/or XFS to compare well with ext2.
