I'm writing a tool to easily compare and merge the configuration between all my gentoo machines, configuration in ALL aspects.

/etc comparison is easy.
/var/lib/portage/world comparision is easy.
kernel config comparision is easy.
grub.cfg comparison is easy.
configuration in user's home directory is not in the scope of this project, this tool is for system configuration only.

Now how can I compare and merge all the eselect settings?
The simplest way I think is to export them into a text file, and import the modified text file after merging.

I might be mistaken but I think all the settings configured via eselect go into /etc/env.d/ ....

I don't think so.

For example:
"eselect kernel set N" changes the soft-link /usr/src/linux
The result of "eselect kernel list" changes after I manually recreate soft-link /usr/src/linux

Yes, using strace on eselect you'll see it actually checks the symlink (in the case of kernel list).
Your tool could just rely on the output of eselect though.

Something like this should do the trick:
Code:
for i in /usr/share/eselect/modules/*; do
    m=`basename $i | sed 's/.eselect//;'`;
    echo $m:;
    eselect $m list;
done


Or, if you're using zsh:
Code:
 for m in /usr/share/eselect/modules/*; do eselect $m:t:r list; done
