Reposting from the puppet list at request.

In addition, it baffles me a bit as to why the default location for grub.conf is
/etc/grub.conf when, on Redhat based distros, it is always in /boot/grub/grub.conf
with a symlink from /etc pointing to it. I think the standard RH installs always
make /boot a separate partition so this lens will never work.

Restoring my edit to /usr/share/augeas/lenses/dist/grub.conf so that it points to
/etc/grub.conf again and running

augtool> set /files/etc/grub.conf/timeout 25
augtool> save
Saving failed
augtool> print /augeas//error/
/augeas/files/etc/sudoers/error = "parse_failed"
/augeas/files/etc/sudoers/error/pos = "2427"
/augeas/files/etc/sudoers/error/line = "66"
/augeas/files/etc/sudoers/error/char = "0"
/augeas/files/etc/sudoers/error/lens = "/usr/share/augeas/lenses/dist/sudoers.aug:480.10-.57"
/augeas/files/etc/sudoers/error/message = "Iterated lens matched less than it should"
/augeas/files/etc/grub.conf/error = "rename_augnew"
/augeas/files/etc/grub.conf/error/message = "Invalid cross-device link"
