This looks unnecessary.

You could merge the 'if [ -d /env/boot.d ]' above with this if/else. The
result would be easier to read IMO.
Also you don't seem to catch the case when no /env/boot.d/* exist and
nothing is given on the command line.

This x quirk is not necessary anymore. Do if [ "$sequence" = y ]
instead.

s/failled/failed/

You could add the missing whitespace between 'exist' and 'valid'
