Ian M.: please arrange for the environment variable "DPKG_NO_TSTP" to be set to some non-empty value (like "yes") when dselect is invoked in this way. This will cause dpkg to invoke "$SHELL -i" instead (or "sh -i" if SHELL isn't set). This feature will be in 0.93.79. Of course, any conffiles prompts at this stage reflect bugs in the base disks.

That would certainly break in this case. Probably we need a flag to dpkg/dselect to change this behavior.

I had a bug report like this before. Can you reproduce it ? If you have two .deb files which have different versions of a conffile in it you can keep getting dpkg to prompt by editing the conffile once and then never answering `y' as you install them alternately. Were you doing this in the dselect automatically started after installing the base system? In this case, dselect is started from a shell script (namely, /root/.bash_profile).

I had a bug report like this before. Can you reproduce it ? If you have two .deb files which have different versions of a conffile in it you can keep getting dpkg to prompt by editing the conffile once and then never answering `y' as you install them alternately. I can't reproduce the problem on my system. I've tried it on the console, in an xterm and on a serial terminal running a getty_ps (hacked not to set SIGPIPE to SIG_IGN in the login process); I've tried it with bash and with tcsh. None of these things have been helpful. Is there anything at all odd about your configuration ? What kernel version do you have ? I'm running 1.2.13, but the problem didn't appear with 1.2.10 either. What is /bin/sh on your system ? > I had to quit dselect, manually kill dpkg, find and remove the lock > file, and then start dselect again. The good news is that my system > survived the whole episode intact! Phew :) I should hope it survived the episode. If you find that dselect and/or dpkg don't recover the system properly when they die or are killed then that is a bug - though you may need to reinstall some .deb files to get all the packages in sane and consistent states.

Ian, you'll know if you changed anything about this. I was using dselect for the first time (for real), and it is very, very nice. However, while it was upgrading my bash.deb, it stopped to query about the confile '/etc/profile'. Fair enough, it was different. I chose the 'Z' (?) option to suspend and investigate for myself. dpkg was then stopped, but instead of starting a shell, it returned to the dselect menu, after which I couldn't do anything, as dpkg was locked. I had to quit dselect, manually kill dpkg, find and remove the lock file, and then start dselect again. The good news is that my system survived the whole episode intact!
