Hi all,
I am maintaining a work-in-progress package [1] for the NetBSD package
system, pkgsrc. I was wondering how to avoid conflict between GRUB
Legacy and GRUB 2, letting them (their userspace utilities) coexist
side-by-side. IIRC, one single utility that was conflicting was
grub-install.

[2] http://www.pkgsrc.org/
>From my point of view, the best solution was to use the autoconf macro
AC_ARG_PROGRAM adding program name transformation options,
--program-transform-name, --program-prefix and --program-suffix. Side
effect of this is that it allows you to have multiple instances of GRUB
2 installed more comfortably.
The question is whether it is a good thing to transform program names by
default in vendor specific packages (as is done with current version of
pkgsrc package). Alternative solution would be to transform GRUB Legacy
filenames, which, though it might cause some confusion to Legacy users,
seems to be more appropropriate. Does GRUB Legacy support such
transformations in its most recent version?
Anone has other/better suggestions how to avoid GRUB Legacy/GRUB 2
conflict? I attach the patch which applies against current CVS snapshot
to this message.
Regards,
