I would expect to do this. Also, you should be converting to ext4 not
ext3. In fact, your kernel probably doesn't even have ext3 in it
anymore. Standard kernels now use the ext4 code for ext3 mounts.</pre>

<br>
One thing at a time... ;)<br>
<br>
It is working now, and currently has ext3 in the fstab. I'd rather
not change that at the same time as doing something like this.<br>

Concerns no. Lack of terror, yes. You will no longer be exposed to

<br>
Yes, I've read the horror stories. I've also had this system running
for 8+ years, and had 2 hard resets (and successful fscks) during
this time...<br>
<br>
There is a lot of FUD about reiserfs.<br>
<br>
Not saying it is perfect, or that your concerns are misplaced (my
new system will use xfs instead), but it isn't as bad as you're
making out... ;)<br>

Nonsense. --numeric-ids disables the ownership translation between
2
different systems when rsync is networking. When you are booted
from
a live environment you still only have 1 user database. It might
disagree with the one you normally boot from but you still have
only 1
so there is nothing to translate.</blockquote>

Ok, well, like I said, since it doesn't matter, that is an argument
I may pursue later, if I fell a need...<br>

I know, but this system was built over 8 years ago (when gentoo
still recommended reiserfs), and runs like a champ, so no desire to
'fix what ain't broke'... anyway, acls are not enabled on it, so no
worries...
</pre>
</blockquote>
<pre wrap="">
If you ever have an instance where reiserfs needs an fsck you may as
well reformat and restore. Reiserfs's fsck just deletes almost
everything then declares success. Reiserfs was never recommended
except for /usr/portage which can always be re-downloaded. It should
absolutely never be used for anything important.</pre>
</blockquote>
<br>
Sorry Kevin, this is just plain BS.<br>
<br>
When I installed gentoo, it was recommended for things like mail
storage when you were using maildir (lots of small files)...<br>
<br>
And as I said, my experience directly refutes your silly claim that
"Reiserfs's fsck just deletes almost<br>
everything then declares success".<br>
<br>
It has had its problems, and indeed may under certain circumstances
be more likely to experience unrecoverable damage to the filesystem,
but most serious problems it has had were fixed fairly quickly (but
maybe not after lots of people got bit). The fact is ext4 has had
its problems and horror stories too, just as xfs and every other
filesystem out there. It is best to stick to verifiable facts when
discussing things like this.<br>

After you finish with this, try adding caps to that. It is a

Any pointers to docs explaining how/why? I'll google later, but I'm
