My recommendation is, if you're a n00b or have any data you simply don't want to lose in random FS bugs, don't move to ext4. I've not had any trouble myself with ext4, but that doesn't mean you won't. Two things I should reiterate. One, don't use on a production system unless you have reliable backups and downtime isn't an issue. Two, don't upgrade the fs on /boot to ext4. At least not yet. -- Mark Haney <a href="mailto:mhaney@ercbroadband.org">mhaney@ercbroadband.org</a> Fedora release 9 (Sulphur) Kernel: 2.6.27.9-73.fc9.i686 GNU/Linux 06:48:33 up 11 days, 11:54, 2 users, load average: 0.28, 0.18, 0.11 -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>got it! thank you!
