/bin/csh is not statically linked. /rescue/csh is. > can help you out in a jam, whereas pointing way off to > /usr/local/bin/bash could spell trouble if say, you can not mount > /usr. More likely trouble scenario is gettext library version bump. However, bash can be statically compiled by the port and you can also set $PREFIX to /, so it gets installed as /bin/bash. That said, you should before you change root's shell have dealt with a broken root shell a few times, to be able to ascertain whether this extra problem is something you want to deal with, at the times you already have a more pressing problem to solve. > > As prad pointed out, you can "su -m". I myself prefer "sudo -s". Unfortunately, sudo -i is not a substitute for su -l, as sudo tries to be more secure then it should be, cleaning the environment, preserving PATH, rather then taking the correct values from /etc/login.conf. Most notably tilde and dollar sign expansion, which are great *shell-independant* features: $ grep setenv /etc/login.conf :setenv=MAIL=/var/mail/$,BLOCKSIZE=M,FTP_PASSIVE_MODE=YES,PACKAGES=/var/pkg/7-stable,PKG_PATH=/var/pkg/7-stable\c. \c/home/$/packages,CCACHE_DIR=/var/db/ccache/$:\ $ echo {$CCACHE_DIR:=No} /var/db/ccache/mel $ echo $MAIL /var/mail/mel $ sudo -c root -i # echo ${CCACHE_DIR:=No} No # echo $MAIL /var/mail/mel -- Mel Problem with today's modular software: they start with the modules and never get to the software part. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
