[Bio-Linux] Live Bio-Linux not persistent

[Cox, Michael J]

Dear All,

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:

linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper persistent quite splash —

now renders the sticks persistent.  In addition I can now see the data and tutorials that Tim loaded for me in /home.

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.

Thanks

Mike

Hi All,

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.

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.

The additional R packages that Tim added to the distribution (dev version of PhyloSeq) are present and correct, so that at least has stayed.

I have checked in:

/syslinux/txt.cfg

and this seems correct - the persistent flag is set on the Try Bio-Linux 7 option:

default live
label live
 menu label ^Try Bio-Linux 7 without installing
 kernel /casper/vmlinuz.efi
 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 --
label live-install
 menu label ^Install Bio-Linux 7
 kernel /casper/vmlinuz.efi
 append noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash --
label check
 menu label ^Check stick for defects
 kernel /casper/vmlinuz.efi
 append  boot=casper noprompt integrity-check initrd=/casper/initrd.lz quiet splash --
label memtest
 menu label Test ^memory
 kernel /install/mt86plus
label hd
 menu label ^Boot from first hard disk
 localboot 0x80

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.

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.

Thanks very much for your help

Mike
