Okay, the next version of apt (.14) will order so that bash is directly after the install of libreadlineg2 and that netbase/netstd is after that. I have also emailed Guy about making libreadlineg2 not depend on bash (C postinst). However - there is no rule that says this is the only solution, it is possible for a package to get inserted between bash and libreadlineg2 - but that is not likely with the current configuration of hamm. (Remeber that bash is not the only package that breaks when libreadline2 is removed, netstd, gdb and libreadline2-dev also do as well, bash will win out because it starts with 'b' and is essential - hardly ideal.) Removing packages that essential packages depend on will always be a risky problem :< A similar problem will occure if someone attempts to remove libc5 when the target system is all libc6 - this situation is actually impossible to deal with, you MUST upgrade libc5 before you can remove it. NOTE: Things are much safer so long as libreadline2 is not removed while bash is installed. Tomorrow I may try to write a quick routine that warns if you are removing an essential package dependent before you begin. Also, I continue to advocate the use of 'apt-get dist-upgrade' over dselect, it will never make these sorts of choices.
