Excluding files while creating a squashfs file

The -e flag will exclude files and folders:

    $ sudo mksquashfs /etc test.squashfs -e /etc/passwd /etc/shadow

The -e option excludes /etc/passwd and /etc/shadow files from the squashfs filesystem.

The -ef option reads a file with a list of files to exclude:

    $ cat excludelist
    /etc/passwd
    /etc/shadow

    $ sudo mksquashfs /etc test.squashfs -ef excludelist

If we want to support wildcards in excludes lists, use -wildcard as an argument.
