[Nix-dev] Re: Problem installing vim-7.2-huge-X11-python-tcl.drv

[Jeevakan Suresh]

Thanks for the tips guys.

My kernel version is 2.6.18-92.el5PAE

Maybe I've missed the point - but would it be sufficient if I built
everything from source (so used the nix repos for build description and
source downloads only)

It may take longer to bootstrap - but at least everything will be
relatively 'pure'.

Speaking of which - is their a command line argument to force all
dependencies to be built from source - I couldn't find one? (ie. The
opposite of --prebuilt-only).

I'm sorry, but I don't have a proper citation handy. I'd have to search
for it, too.

Well, I guess you are right. If you want an ultra-safe-no-risk-at-all
installation, then rebuilding every single package after every kernel
update is the way to go. It's just that I, personally, don't want that.
In my humble opinion, the kernel/libc/coreutils authors do a fine job at
maintaining backwards compatibility across minor revisions, so I'm
willing to take that risk. Others might not. It's nice that Nix offers
us the means to build both kinds of installation.

For starters, we can apply the patch that you posted to this list. All
that seems to be missing is a volunteer to do it.

Take care,
Peter
