SEUNSHARE(8)                  User Commands                 SEUNSHARE(8)

NAME

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

SYNOPSIS

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

DESCRIPTION

       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.

       -t tmpdir
              Use alternate temporary directory to mount on /tmp.
              tmpdir 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.

       -k --kill
              Kill all processes with matching MCS level.

       -Z context
              Use alternate SELinux context while running the
              executable.
