Right, it should've been:
sudo echo "* * * * *  root  /bin/sync" >> /etc/crontab

I always use ext3[*] and I do cron-syncing in distro (Debian, Mandrake,
Kanotix, Kubuntu ...) for any system (servers as well as desktops except
live-distros) :)

I'm not sure what added benefit reiserfs would bring regarding FS
resilience against crashes, though. Theoretically, ext3 or reiserfs ought
to be equally resilient, and yes cron-syncing defeats (or more precisely,
it's superfluous) the purpose of already in-place kernel mechanisms. But
then again, it works and it has virtually no adverse effect on
performance.

[*] BTW I wonder why a single-CD distro like Kubuntu should include support
for any FS under the Sun. I can understand ext3, reiserfs, fat32, and
ntfs. But what good is it to have jfs, xfs, etc marginally used FS
supports on the space starvant CD? It's even concievable to let either
ext3 or reiser go (the one which has less user base). Then, root FS will
have to be either ext3 or reiser, depending on which FS is included in the
CD. If the user has already existing partitions with other FS (minority
case), then he can always post-install the support for it. However, this
is a far future issue for now, given there are even less relevant packages
on the CD for casual desktop usage, and given the Hoary CD is not even
filled up to 700M.
