Dear All,
<div><br>
</div>
<div>I think I fixed this, when I checked /boot/grub/grub.cfg there was no persistent flag. Adding this to the first menu entry line:</div>
<div><br>
</div>
<div>linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper <b>persistent</b> quite splash —</div>
<div><br>
</div>
<div>now renders the sticks persistent. In addition I can now see the data and tutorials that Tim loaded for me in /home. </div>
<div><br>
</div>
<div>It does take a little longer to load and is slow initially, so I have some concerns that I have done something less than ideal. Comments appreciated.</div>
<div><br>
</div>
<div>Thanks</div>
<div><br>
</div>
<div>Mike</div>

Hi All,<br>
<br>
we?re using live USBs for a course next week that Tim kindly cloned after installing a couple of R packages and a test dataset. He?s now on his hols, so I thought I?d check to see whether the rest of the list could help me with an issue that I?m having.<br>
<br>
On boot, I couldn?t find the data that Tim added. I?ve checked by creating a file and the sticks aren?t persistent and files are removed when the USB stick is. I did find a reference that suggested creating a new user and that user account would be persistent,
but no joy, new user and file removed on reboot.<br>
<br>
The additional R packages that Tim added to the distribution (dev version of PhyloSeq) are present and correct, so that at least has stayed.<br>
<br>
I have checked in:<br>
<br>
/syslinux/txt.cfg<br>
<br>
and this seems correct - the persistent flag is set on the Try Bio-Linux 7 option:<br>
<br>
default live<br>
label live<br>
menu label ^Try Bio-Linux 7 without installing<br>
kernel /casper/vmlinuz.efi<br>
append noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash locale=en_GB.UTF-8 --<br>
label live-install<br>
menu label ^Install Bio-Linux 7<br>
kernel /casper/vmlinuz.efi<br>
append noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash --<br>
label check<br>
menu label ^Check stick for defects<br>
kernel /casper/vmlinuz.efi<br>
append boot=casper noprompt integrity-check initrd=/casper/initrd.lz quiet splash --<br>
label memtest<br>
menu label Test ^memory<br>
kernel /install/mt86plus<br>
label hd<br>
menu label ^Boot from first hard disk<br>
localboot 0x80<br>
<br>
This post http://ubuntuforums.org/showthread.php?t=2124124&p=12551088#post12551088 suggests editing syslinux.cfg (rather than txt.cfg) to make a Ubuntu stick persistent, which I?ve tried, but it booted up exactly as before and again was stubbornly resistant
to retaining files.<br>
<br>
Can anyone suggest ways to get this working? Given the fact the R packages have remained, some aspect of this seems to be functioning? I could have the attendees download the data and course material, but would much rather they left with a copy of Bio-Linux
and all their work and notes in one elegant package.<br>
<br>
Thanks very much for your help<br>
