<vagrantc>
gah. the kernel cleanup code seems borked.

vagrantc: hi! I'm at work, but I don't have too much time for ltsp now... want me to review anything quickly?
06:52
david007co2: you can pxe boot from a windows server too
06:54
vagrantc: VAR="1 2 3 *" doesn't use shell globbing, it doesn't get expanded there
06:55
But if you use it in for var in $VAR, there it will get expanded
06:57
See the kernel_split() function, there I needed to use it inside a `for` so I disabled glob expansion, # Disable glob expansion for this function set -f

<vagrantc>
alkisg: well, when i did some debugging, the ": $LIST_KERNELS" was expanded.
08:57
<alkisg>
vagrantc: you did put a "for" without "set -f" there though, maybe it was that?
08:58
<vagrantc>
alkisg: no, outside of the loop it was showing an expanded variable
08:58
<alkisg>
with "echo $VAR" ?
08:58
<vagrantc>
: $VAR
08:58
<alkisg>
it needs to be echo "$VAR", quoted
08:58
<vagrantc>
which i guess was expanding at that point
08:58
<alkisg>
Otherwise it gets expanded when you run echo
08:59
<vagrantc>
well, I needed it in another loop anyways
09:00
<alkisg>
Anyways that's a detail, if you prefer "ALL" to "*", no problem from me
09:01
But after jessie I think we still need to review the ifcpu64 related code
09:01
<vagrantc>
what would make more sense is to have that for chroot selection
09:01
<alkisg>
I propose we do it like I said yesterday, to create one symlink for each flavor, and leave all advanced things for the sysadmin
09:02
(i.e. only to remove code, not add)
09:02
E.g. maybe debian can ship an example about how to use ifcpu64
09:02
...which doesn't apply in ubuntu
09:03
<vagrantc>
well, it would be useful in ubuntu to select between an i386 chroot and amd64 chroot
09:03
single pxelinux boot file that spans chroots
09:03
(or NBD images, or AOE, etc.)
09:03
<alkisg>
yes, but that's not something that ltsp can do easily, the sysadmin can do it though
09:04
The kernel names for i386/amd64 are the same
09:04
So ltsp would need to check /etc/issue, dpkg --print-architecture inside the chroot and other funny stuff
09:04
At that point I'm inclined to leave it up to the sysadmin, to stop "automating" things :)
09:05
And, our pxelinux.cfg/default couldn't point to 2 chroots anyways
09:05
<vagrantc>
dunno, it seems so automatable to me, seems silly to have multiple people do it.
09:06
<alkisg>
The sysadmin would do that in /var/lib/tftpboot/pxelinux.cfg/default, not in ltsp/chroot/pxelinux.cfg/default
09:06
<vagrantc>
sure
09:06
<alkisg>
We can put some code in ltsp-config if you like
09:06
But I really don't think it's a task for update-kernels
09:06
<vagrantc>
that's always an easy answer :)
09:07
i've got patches for arm almost sorted out, although could push what I have if needed.
09:08
<alkisg>
E.g. ltsp-config pxelinux: only use it if you have multiple chroots. It creates a "master pxelinux.cfg/default" file that you can customize... etc etc
09:08
..and a --overwrite option
09:08
...although that would require changing dnsmasq/dhcpd too
09:09
<vagrantc>
alkisg: well, i'd best not get drawn into another late discussion... :)
09:09* vagrantc waves

<alkisg>
(11:06:15 πμ) vagrantc: dunno, it seems so automatable to me, seems silly to have multiple people do it.
09:09
==> /me doesn't think it's so much automatable :)
09:09
Good night!
09:10
<vagrantc>
alkisg: till next time! :)
