Documentation suggests that ext2 and ext3 filesystems may be converted: https://ext4.wiki.kernel.org/index.php/Ext4_Howto
I have not tried this myself though.

For simply ext4 support in kernel: Kernel 2.6.31.8 on my VL box mounts and reads it just fine. After upgrading e2fsprogs to version 1.41.3 (sw 12.2) I can also create ext4 systems.

As far as your root filesystem.. I agree with M0E-lnx; pick a version that supports ext4 during installation. Converting afterwards would be complicated. I really don't see any good reason to do so.

[M0E-lnx]

I've tried this on, not exactly on a VL install, but on my android phone, and migrating from from ext2/3 to ext4 has left me with undesired side effects that forced me to wipe the thing and re-do it with < ext4

@nightflier: Thank you! I only needed to be able to read partitions formated with the ext4. I forgot I can install Vector light on ext3, THEN upgrade the kernel and make it read and write other ext4 partitions. Am I correct? Besides, ext3 uses slightly less resources it seems?

@Drazen: Correct. An upgrade to kernel 2.6.31.8 will give you the ability to access ext4 partitions. Follow this guide:

If you also want to be able to create ext4 filesystems, upgrade your e2fsprogs using this package:

This article highlights some of the performance differences between ext3 and ext4:

It also illustrates our difference in opinion regarding what hardware is considered "antiquated"
