| 06:50 | work_alkisg is now known as alkisg | |
| 06:51 | <alkisg> 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

| 08:57 | <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 | |
| 09:09 | <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! :)
