Thread: Persistent live wan't work after moving casper-rw

hi,
want use 32gb usb memory live ubuntu persistence.
initially, tried within ubuntu (12.04-386), boot.
afterwards used gparted create 3 partitions on above usb memory:
1 bootable 3.8gb fat32 partition labeled ubuntu
2. 3.8 gb far32 partition labeled windows (for data exchange between oss)
3. large (rest of un allocated space) ext2 partition labeled casper-rw.

used unetbootin create persistent ubuntu (same version) on ubuntu partition.

rebooted , verified usb worked (i able boot ubuntu).

rebooted (into arch) and, root, used "rsync-av" move contents has been in casper-rw folder (in ubuntu partition) otherwise entry large casper-rw partition. afterwards deleted folder casper-rw (and contents) ubuntu partition.

trying reboot usb, following error: "initrmfs unable find media containing live filesystem".

below see terminal out of current structure , contents of usb memory.

please advise!

thanks

you must have done wrong. files not belong in casper-rw. when loop mount casper-rw file on /media/vdisk:

code:

efflandt@xps8100-1204:/media/vdisk$ ls -l total 68 drwxr-xr-x  3 root root  4096 apr 25 11:10 boot drwxr-xr-x  2 root root  4096 jul  8 08:44 cdrom drwxr-xr-x 13 root root  4096 jul 21 20:49 etc drwxr-xr-x  3 root root  4096 jul  8 08:44 home drwxr-xr-x  3 root root  4096 apr 25 11:08 lib drwx------  2 root root 16384 jul  8 13:26 lost+found drwxr-xr-x  2 root root  4096 jul  8 19:09 media drwxr-xr-x  4 root root  4096 jul 21 20:38 mnt drwxr-xr-x  2 root root  4096 jul  8 08:44 rofs drwx------  6 root root  4096 jul  8 13:57 root drwxr-xr-x  2 root root  4096 jul  8 14:02 target drwxrwxrwt  7 root root  4096 jul 21 13:56 tmp drwxr-xr-x  6 root root  4096 apr 25 11:04 usr drwxr-xr-x  7 root root  4096 jul 21 20:49 var

you apparently copied files "casper" directory, instead of loop mounting "casper-rw" , copying contents of that:

code:

efflandt@xps8100-1204:/media/vdisk$ ls -l /media/ec19-c886/casper total 698876 -rw-r--r-- 1 efflandt efflandt     41031 jul  8 08:19 filesystem.manifest -rw-r--r-- 1 efflandt efflandt       971 jul  8 08:19 filesystem.manifest-remove -rw-r--r-- 1 efflandt efflandt        11 jul  8 08:19 filesystem.size -rw-r--r-- 1 efflandt efflandt 695623680 jul  8 13:20 filesystem.squashfs -rw-r--r-- 1 efflandt efflandt  14999791 jul  8 13:20 initrd.lz -rw-r--r-- 1 efflandt efflandt   4965840 jul  8 08:20 vmlinuz

however, have never figured out how live/install iso use separate partition labelled "casper-rw", maybe because did not know copy contents of loop mounted casper-rw it.

btw ext2 better use flash memory (less writing journal file system). , if have 32 gb, why not regular install it, can kernel updates, or if need non-default video drivers? compare, installed both 64-bit lubuntu , ubuntu 12.04 common /home partition 32 gb sd tablet pc.
