That's rather far from actually fixing the problem. Can we get it

Obviously dropping the caching would be pretty nasty. Having to dlopen
the modules each time you do a getpwnam() (or friends) isn't cool.
I assume you mean fstating the file on each lookup? I'm not against
this, and I can try and propose this to glibc, but I'm pretty sure
what's going to happen. See similar /etc/resolv.conf discussions.
or by
modify authconfig to instruct the user to reboot after changing
/etc/nsswitch.conf .
That's *really* ugly, and prevents tools (like ipa-client-install or
realmd) from completing an initialization in one shot. They would have
to be split into two parts, with a reboot in between. :S
I'm not opposed to changing the default nsswitch.conf to avoid that
reboot (well, I think it's ugly to refer to a non-installed module,
but that's an aesthetic, not a principal thing) and to improve the
user experience in the default case, but we do need to have some way
to fix the underlying problem, a better way than just giving up and
conceding that nsswitch.conf can't be edited from now on.
We are working on it and I linked to that bug in my report. Ray Strode
and I are working on patches to glibc.

Obviously, if you have another idea of how to fix this other than the
above, this would be a great place to put it forward.
