anybody who managed to forcibly remove nss-softokn wile try to solve
dependency problems with a hammer and after that find out that nearly
*anything* on the system needs this package knows why

* rpm is dead
* yum is dead
* sshd is dead

in my case i managed it on that time by samba having a hidden root account*
and restore each file manually because boot from live media and chroot did
also no longer work (after chroot the same problems)

after that you understand why things are protected and that you should
hardly avoid try to bypass them until you are 1000% sure what you are
doing and there is no other way

yes this is many years ago and these days i would setup a
smb-root acccount only over my dead body
