<alkisg>
vagrantc: `ltsp ipxe` needs {memtest.0,memtest.efi,undionly.kpxe,snponly.efi} from boot.ipxe.org; they're not provided by debian packages,
20:08
so, I thought it best to clone them periodically in github, make binary releases there, and have `ltsp ipxe` wget them to TFTP_DIR/ltsp
20:08
https://github.com/ltsp/binaries/releases
20:08
(ignore sshfs there, this is only for live cds that don't have sshfs, I'll probably remove it on production)
20:09
Is it acceptable to wget things when the sysadmin runs `ltsp ipxe`?
20:11
<vagrantc>
acceptible, if not ... great
20:11
ideally would have another option, though...
20:11
can we rebuild or add to ipxe packaged versions?
20:12
<alkisg>
I'll file bug reports in distributions to generate those from the ipxe sources into the ipxe deb files, but until then...
20:12
And it will certainly won't make it to live CDs < 2020
20:12
So we need some way to function until then
20:12
<vagrantc>
the memtest we could manage without, obviously
20:12
the others are definitely necessary?
20:13
<alkisg>
Yes; well, one could also use ipxe.efi or ipxe.lkrn, but they're a lot larger and somewhat different
20:14
E.g. they default to using the internal ipxe drivers instead of the ones provided by the nic stack
20:14
<vagrantc>
those files even look familiar; does memtest86+ in debian ship them?
20:14
<alkisg>
memtest.0 is for pxe; memtest86+ may fail under pxe
20:14
It's a special fork, made by the ipxe author
20:15
<vagrantc>
i see
20:15
<alkisg>
From the code: # Prefer memtest.0 from ipxe.org over the one from distributions:
20:15
# https://lists.ipxe.org/pipermail/ipxe-devel/2012-August/001731.html
20:17
The ltsp ipxe script and the ipxe configuration file: https://github.com/eellak/gsoc2019-ltsp/tree/master/ltsp/server/ipxe
20:17
I simplified ltsp.ipxe a lot, I think it's quite readable now
20:18
I intentionally only give the users a few static choices; they're supposed to either name their VMs that way, or manually edit ltsp.ipxe after it's created
20:19
Since we can put hostnames and kernel parameters there, it'll substitute most of the old lts.conf/pxelinux uses, so it shouldn't be regenerated frequently
