| 09:46 | <vsuojanen[m]> I wonder if anyone have ever for image source copied a running livecd root to local disk and then within same livecd session installed ltsp and have the local disk nfs exported for pxe client nfsroot (rw)? is the chroot even possible to setup without downloading and moutning another copy of the livecd image?
| |
| 09:48 | <alkisg> vsuojanen: if you put ubuntu.iso to /srv/ltsp/images/x86_64.img, and run ltsp-kernel, then the clients boot
| |
| 09:48 | No ltsp image is necessary
| |
| 09:48 | <vsuojanen[m]> * chroot was just a term, not needed actually
| |
| 09:51 | <alkisg> While if you mean that you want to run ltsp FROM a live cd, sure that's also doable, just bind-mount it to /srv/ltsp/images/x86_64.img and install ltsp and run ltsp kernel etc
| |
| 09:54 | <vsuojanen[m]> i was thinking image preparation so as chroot directories but there is administrative client that gets the nfsroot_rw netbooting. livecd running -> rlivecd ootfs copid to sda1 -> nfs export (sda /) --> pxe adminstrative client -> finish the image in nfs_rw --> shutdown the administrative client --> the image source is stored on local disk in the machine that booted the livecd
| |
| 09:55 | http://ltsp.org/docs/installation/raspios/
| |
| 09:56 | <alkisg> Sure, you can set ADMINISTRATIVE_CLIENT in any OS, not just on raspios
| |
| 10:04 | <vsuojanen[m]> but without any servers could the livecd running root filesystem be copied to machines empty local disk and is it usable for nfsroot export then within same livecd session ? livecd is booted and left running as ltsp server where one nfs_rw exports the files that were copied to local disk (mounted in livecd sesson e.x. /mnt)
| |
| 10:11 | use case e.x. you visit another network/building, boot a livecd for one or two administrative client(s), they boot and while in nfs_rw , the administrators finnish their work without creating the image, then you do what ever you want with that image source they created
| |
| 10:11 | <alkisg> Yes, sudo mount --bind /isodevice/casper/filesystem.squashfs /srv/ltsp/images/x86_64.img && sudo ltsp kernel
| |
| 10:15 | <vsuojanen[m]> but the isodevice needs to be downloaded mounted in the running filesystem before bind mounting for the administratvie clients?
| |
| 10:20 | i had not yet took a look for this... checked...
| |
| 10:20 | did you mean e.x. ls -1 /cdrom/casper/filesystem.squashfs
| |
| 10:20 | /cdrom/casper/filesystem.squashfs
| |
| 10:20 | ubuntu-unity@ubuntu-unity:~$
| |
| 10:20 | ?
| |
| 10:22 | <alkisg> Yes, that one
| |
| 10:25 | <vsuojanen[m]> thanks, or let's hope I don't need that but if I have time I think it's a one topic for learning
