cvsd binary package in Ubuntu Bionic s390x

 cvsd is a wrapper program for cvs in pserver mode. it will run 'cvs pserver'
 under a special uid/gid in a chroot jail. cvsd is run as a daemon and is
 controlled through a configuration file. It is relatively easy to configure
 and provides tools for setting up a rootjail.
 .
 This server can be useful if you want to run a public cvs pserver. You
 should however be aware of the security limitations of running a cvs
 pserver. If you want any kind of authentication you should really consider
 using secure shell as a secure authentication mechanism and transport.
 Passwords used with cvs pserver are transmitted in plaintext.
 .
 You should probably disable the pserver from the cvs package.
