Right.  But that's a list that will continually need updating as new
packages are brought in.  As I said in a previous message, having
package maintainers identify config files within their packaging is
still error-prone but probably less so than them having to know/remember
to upgrade the "sysupgrade list".

Yes.  That one seems quite obvious.  Unfortunately, not all packages are
uci driven [yet].

So sysupgrade also takes care to restore the saved config,
automatically?  Does it do this on reboot?  I might have to go
investigate this sysupgrade more closely.  I think the last time I
looked at it though it didn't support much outside of x86 based systems
though.

So how do I know which ones specifically that is?

Yes, absolutely.  They all should though, where there is common
functionality.

Well, this is good news then.  Maybe time to look at that again.

Thanx for the clarification.
