Re: bug report: attributes ( chattr +a ) not respected by reiserfs 3,6, but this isn't listed in man mkreiserfs

["D.A.M. Revok" <marvin@synapse.net>]

I was absolutely stunned that reiserfs would throw-away attributes
/by default/ but possibly it could know them?

So, I tried

su
	mount -o remount,attrs /mnt/md1
exit
echo "this and that" > test
su
	chattr +a test
	lsattr test		# *same as before*, it lists the attribute
exit
cp /dev/null test
ls -l test			# answer is size==0

So now ( now that I found your e-mail in all these damn spams! )
I know that it doesn't respect attributes normally, or with the
mount -o attrs
option.

It /shows/ that it respects attributes, but they don't /change anything/
and that is a problem.

Append-only logs work in ext3, but not with reiserfs.
