I am using ubuntu server 14.04.1 and i want edit filesystem.squashfs after installed squashfs-tools and unsquashfs and edit filesystem and mksquashfs and build iso i get this error

base-installer: info: Using squashfs support for /cdrom/install/filesystem.squashfs

i think this error becouse kernel version not equal squashfs-tools

is this right ?

and i want install right package squashfs-tools support kernel ubuntu-server 14.04.1

and sorry if my english is bad

Solution 1:

The "answer" to your question is: The message " getfattr: [file name]: Operation not supported" is because squashfs does not support ACL.

https://help.ubuntu.com/community/FilePermissionsACLs

and http://manpages.ubuntu.com/manpages/trusty/man1/getfattr.1.html

getfattr - get extended attributes of filesystem objects

For each file, getfattr displays the file name, and the set of extended attribute names (and optionally values) which are associated with that file.

So, because squashfs does not support ACL or "extended attributes" , you are getting the message " getfattr: [file name]: Operation not supported", the files in your squashfs do not have extended attributes, period. The never will no matter what version of squashfs you use.

See https://www.kernel.org/doc/Documentation/filesystems/squashfs.txt

ACL support: no no

In order to not get that message, don't use ACL.

That message has nothing to do with kernel version on version of squashfs-tools as you are asking in "i think this error becouse kernel version not equal squashfs-tools"

I am not sure how that affects your custom iso it should still boot just fine as ACL are not mandatory to boot or run Ubuntu and most people do not use them.

If you are having a problem with your custom iso you need to provide details of how you made it.

What was your base .iso ? What customization did you make ? and best, what command did you use to both make the squashfs and iso ?

Other than explain the cause of the message it is impossible to provide any further support due to the lack of information you have posted despite extended discussion.
