It seems to me (particularly from the fact that you upgraded a grub2 bug report about this to important - GRUB 2 does not store block lists for kernels) that this is not limited to boot loaders that store block lists for the files they load: it also affects boot loaders that need to be updated whenever the *list* of files they load is modified. Can you confirm that my understanding is correct? > 2.

This is going to be quite a lot of calls to update-grub if so, although at least it's quite a bit faster now than it used to be ... > 3.

It seems like a waste of time calling boot loader hooks otherwise. (This may be implied by your design, but it was a little bit implicit if so.) > 4.

[Is this sensible or is it too 'clever'?] Sensible, I think. There's no point running update-grub three times. -- Colin Watson [cjwat...@debian.org] -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
