Hi,
here are some unrelated issues about cdebconf.
1. The helper macros recently introduced do break several packages
under debian-installer/tools/ which used to declare their own
debconf_input function. Maybe we could remove these macros, I
wonder whether they are that useful.
2. The attached backup.patch finishes support for backing up. As it
slightly changes cdebconf interface, I prefer sending it there.
3. May I set a _ macro in frontend.h in order to start i18n of
frontends? As libdiscover already calls dcgettext, I would like to
set it to
#define _(x) dcgettext("cdebconf", (x), LC_MESSAGES)
4. As esplained in #172218, current TITLE command is not l10n-friendly.
I will wait for Joey's solution before changing this in cdebconf, but
the new progress bar support suffers from the same problem.
