During upgrades all library link kits are now removed early on - right after mounting the file systems. This leaves a number of questions where the user can choose to abort the upgrade, or possibilities for things to go wrong. In such cases, or if the user makes any choice of sets not including base*.tgz, library relinking will be broken on next boot.
I think we should only remove these link kits if we know that a new one will be installed: Index: install.sub =================================================================== RCS file: /var/cvs/src/distrib/miniroot/install.sub,v retrieving revision 1.1110 diff -u -p -r1.1110 install.sub --- install.sub 11 Feb 2019 17:51:53 -0000 1.1110 +++ install.sub 1 Mar 2019 19:01:00 -0000 @@ -1640,6 +1640,10 @@ install_files() { return fi + if [[ $MODE == upgrade ]] && isin base$VERSION.tgz $_get_sets; then + rm -f /mnt/usr/share/relink/usr/lib/* + fi + # Install the set files. for _f in $_get_sets; do _fsrc="$_src/$_f" @@ -3168,8 +3172,6 @@ do_upgrade() { # Ensure that previous installer choices (e.g. method) are available. wait_cgiinfo - - rm -f /mnt/usr/share/relink/usr/lib/* # Ask the user for locations, and install whatever sets the user # selected.
