Comment:
I don't think that CMP is a useful replacement.
I would much prefer a tool that produces unified diffs being available for
use in scripting on my router, to perhaps automate configuration merging,
and definitely for interactive work.
Curious: how much space was saved by removing 'diff'? how much less space
is saved by now having 'cmp'? is it a terribly large amount when
considering LZMA?
An update process for a config file that informs me in well-learned manner
of unified diff, which lines are different, and where, is quite a lot more
useful than
root@OpenWrt:~# cmp /etc/config/qos /etc/config/qos-opkg
/etc/config/qos /etc/config/qos-opkg differ: char 120, line 6
Yes, I can go in with vi; but not all changes are shown, and I do not know
what, if anything, past char 120 has changed.
