[bug#39882] [PATCH 0/1] Add kexec-tools.

[Chris Marusich]

Hi,

This simple patch adds kexec-tools.  I've built it successfully on an
x86_64-linux system and confirmed via basic manual testing that kexec
works.  I verified the signature of the upstream release tarball when
adding this.  The patch applies cleanly to commit 6ce086550.

I was kind of surprised to find that kexec-tools was not already
packaged.  Is there a reason why it hasn't been packaged, or am I just
the first one to try packaging it?

Thank you,

Chris

I was also surprised, having installed kexec-tools on Guix before 
;-)

Turns out I never upstreamed it.  There are probably 5 other 
kexec-tools patches somewhere.  Oh well.

Your patch looks good to me.  I prefer the home page below over a 
directory listing.  Feel free to crib what you like.

Your synopsis/description imply that it's boot-Linux-only.  I 
don't think that's the case, but haven't tried others in practice.

Thanks!

Hi Tobias,

Sounds good.  I've gone ahead and committed this in commit
dedbdacf275cb7871c7336bd7a27ceb609b15113 with a few little changes, per
your suggestions.

Glad to know I wasn't missing something :-)

You're probably right.  I've removed the Linux-specific wording.

I didn't know we had mirror config for kernel.org.  I've switched to
using that in the latest patch.

Yes, this home page is better.  I'll use it!

I've changed my synopsis to be more like yours.
