Hi, SL users - I have constructed an SL6 installer USB disk and it works
but after asking all the questions, right before starting to install packages,
it stops and requests that there be an active network connection. The
installation
does not seem to proceed until the machine acquires an internet connection.
Why is this?
How did you make the USB image?
Same as any bootable USB disk. Partition the USB disk, mkfs, rsync bootable
filesystem contents, install boot loader.
As follows:
1) Partition table looks like this:
Disk /dev/sdc: 7996 MB, 7996440576 bytes
224 heads, 56 sectors/track, 1245 cylinders
Units = cylinders of 12544 * 512 = 6422528 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdc1 * 1 1245 7808612 83 Linux
NOTE: you need to repartition with -H224 -S56 (or whatever) because
I see some USB disks come with random heads and sectors settings.
NOTE2: note "boot" flag
2) mke2fs -j /dev/sdc1 as normal, mount /dev/sdc1 /mnt/dst
3) rsync -av /triumfcs/mirror/SL/6.1/x64_64/os /mnt/dst (same contents as
http://ftp.scientificlinux.org/linux/scientific/6.1/x86_64/os)
4) directory "Packages" is probably not needed
5) rsync -av .../SL-61-x86_64-2011-11-09-Everything-DVD1.iso
.../SL-61-x86_64-2011-07-27-Everything-DVD2.iso /mnt/dst
So you should have a /images directory on your usb drive. Copy the
/images/updates.img and /images/product.img from
.../SL-61-x86_64-2011-11-09-Everything-DVD1.iso to /images directory of
the usb drive.
6) cd /mnt/dst, setup "extlinux" (since the original uses isolinux). I use
extlinux, mbr.bin, menu.c32 from extlinux-3.86.
6a) cat mbr.bin > /dev/sdc, ./extlinux -i . (notice the dot)
6b) extlinux.conf is a copy of isolinux.cfg with "vesamenu.c32" replaced by
"menu.c32" from extlinux-3.86
7) umount /dev/sdc, try to boot it.
I am making an SL6 installer for use on machines located where internet
access is physically impossible, so is there a solution or workaround?
There is a solution to this but I need to know the answer to the
above question.
Ideally, I would like the installer run from the "Packages" directory rather
than the DVD iso images.
