modify_inode is the old command, and it is indeed hard to use. The
new one (and the one I use all the time) is set_inode_field
(abbreviation "sif"):

sif /bin/su mode 0104755
sif /bin/su uid 0

BTW, one of the things that I've always toyed with was to create a
shim layer between the libss API and the tcl embedding API, which
would add some scripting, aliases, and automation relatively easily to
debugfs.

What people have done in practice who have cared about this is to
create perl scripts which emits a series of commands which they then
feed to a pipe which has debugfs on the other end.
