in 2.4.x, when using menuconfig, the ext3 module was available only if ext3 was chosen. i didn't see any such behaviour when using gconfig and menuconfig. ext3 could be selected without ext2. just wanted to verify if the configs are right.
It's not safer.. It's required if your root file system is ext3
After all, ext3 is just a journaling extension of ext2 -- It stands to reason that the lower level is required.

in that case gconfig and menuconfig (or whichever file handles the dependencies) has a bug, coz it allows me to choose ext3 without ext2. in menuconfig for 2.4.26 stock kernel of slack10, ext2 and 3 are in different places in the file-system list. for 2.6.8.1 it's independent (but in the same place).
according to the README.initrd by volkerding, ext3 requires jbd (and shows up like that in lsmod also). and this dependency is definitely not taken care of in gconfig and menuconfig.
Well, I wouldn't call it a bug. It's just a little counter-intuitive.
There are lots of things like that -- if you use make menuconfig and hit ? on some options, it will tell you something along the lines of "If you choose this, you should say yes to such and such options below."
Ext3 is one of those.

i'd agree, but read the following part in volkerding's Slackware initrd mini HOWTO:

Here's another example: Build an initrd image using Linux 2.6.7 kernel
modules for a system with an ext3 root partition on /dev/hdb3. Note
that you need both the jbd and ext3 modules to use ext3:
Originally posted by KMcD You only need to do that if you build ext3 support as a module, if you build it directly into the kernel then you do not have to make an initrd image.
ok, but what about the dependecy of ext3 on jdb?
in xconfig, jdb (the first jdb listed) gets selected if u choose ext3.
then it would seem to me that you should build both into the kernel directly. I can't look at my own 2.6.8.1 config at the moment, so I'll have to check it. If your root filesystem is ext3 then I don't think it'd be wise to not build support directly into the kernel.
