I am trying to convert an image of the new UbuntuMATE for the Raspberry Pi to SquashFS for use in berryboot… I am using the instructions directly from the berryboot site for converting the second partition in the 2015-03-14-ubuntumate-vivid.img file…
$ sudo kpartx -av image_you_want_to_convert.img
add map loop0p1 (252:5): 0 117187 linear /dev/loop0 1
add map loop0p2 (252:6): 0 3493888 linear /dev/loop0 118784
$ sudo mount /dev/mapper/loop0p2 /mnt
$ sudo sed -i ‘s/^/dev/mmcblk/#\0/g’ /mnt/etc/fstab
$ sudo mksquashfs /mnt converted_image_for_berryboot.img -comp lzo -e lib/modules
$ sudo umount /mnt
$ sudo kpartx -d image_you_want_to_convert.img
When I run SquashFS I get this output:

The problem is this error:
Unrecognised xattr prefix system.posix_acl_access
The new SquashFS .img is created, but when I install the new image file in berryboot it will not boot… I get this error:
Mounting image Ubuntu_MATE_berryboot.img
Error: unable to locate or execute /sbin/init /usr/lib/systemd/systemd /init inside Ubuntu_MATE_berryboot.img
and it drops me to a squashfs# prompt:
Emergency recovery shell activated
/bin/sh: can’t access tty; job control turned off
/squashfs #
Why won’t this work? Do I need remove the xattr from the entire original image of my UbuntuMATE for Pi ?
If so how do I do that so that SquashFS doesn’t skip packing these folders and files?
Thanks
