Problem with update (CSS) : uninstall packages which reinstall after

Hi,

i installed a new CSS server, and I installed some apps :

net-analyzer/fail2ban
app-editors/vim
dev-db/mariadb
www-servers/apache
dev-lang/php
sys-process/nmon
sys-process/htop
sys-process/glances
sys-apps/inxi
app-admin/rsyslog
logrotate

When i update my system, all is up to date but packages are uninstalled, and installed again …

Hummm bug with calculate-utilities variables …

cl-core-variables --set update.cl_update_other_set=on
cl-core-variables --set update.cl_update_with_bdeps_set=on

and solved

We fixed different behaviour on package updating and preserved rebuild. Now cl-update setups --with-bdeps by variable update.cl_update_with_bdeps_set only.
