Note that you'll still see that "you need a newer e2fsck" message. rhmkiso
understands that condition and deals with it, but it's not possible to tell
e2fsck to not issue that message.

No, brltty doesn't use those devices in any of its drivers. It does all its USB
work via usbfs.

An initrd is executed via the /linuxrc symbolic link. You'll find that that's
now symlinked to brltty.

These warnings are okay. They're new, and I haven't yet figured out how to get
rid of them. They're generated because, even when linking statically, some
portions of glibc, e.g. name service lookups, still load shared plug-ins. The
warnings mean to make sure that you run the static binary on a system which
also provides a compatible copy of the dynamically lodable plug-ins. Nothing
you'll do with brltty will require them, so those warnings, in this case, are
merely an annoyance.

>e2fsck: Filesystem has unsupported feature(s)
>e2fsck: Veuillez obtenir une version plus récente de e2fsck!

You should still expect to see this (see above) as rhmkiso first tries the
simpler way before trying the more complicated way. If you get a brltty.iso
then it's working.
