NAME         top

       seunshare - Run cmd with alternate homedir, tmpdir and/or SELinux

SYNOPSIS         top

       seunshare [ -v ] [ -C ] [ -k ] [ -t tmpdir ] [ -h homedir ] [ -Z
       context ] -- executable [args]

DESCRIPTION         top

       Run the executable within the specified context, using the
       alternate home directory and /tmp directory.  The seunshare
       command unshares from the default namespace, then mounts the
       specified homedir and tmpdir over the default homedir and /tmp.
       Finally it tells the kernel to execute the application under the
       specified SELinux context.

       -h homedir
              Alternate homedir to be used by the application.  Homedir
              must be owned by the user.

       -r runuserdir
              Use alternate temporary directory to mount on
              XDG_RUNTIME_DIR (/run/user/$UID). runuserdir must be owned
              by the user.

       -C --capabilities
              Allow apps executed within the namespace to use
              capabilities.  Default is no capabilities.
