Dselect / dpkg interaction.
After talking to Stephen Tweedie <sct@dcs.ed.ac.uk> last night about
my understansing of the current way which dselect and dpkg handle the
'Z' conffiles option, he came up with one possible solution I thought
should be aired.
At the moment, dselect sets an environment variable, and dpkg then
tests this and spawns a new shell if appropriate. Is that correct?
Stephen suggests that dselect should trap the SIGSTOP from dpkg, and
not treat it as a SIGTERM. dselect should then send itself a SIGSTOP,
followed by a SIGCONT. This means the signals are propogated back to
the originating shell, altogether cleaner and less resource hungry.
Ian, do you think this is a Good Thing?
Just a thought for some mulling....
Kenny.
