CRIUスキャンでUbuntu ServerプラットフォームのRaspberry-Pi-4（4 GBバージョン）に警告が表示される

Warn  (criu/cr-check.c:680): Dirty tracking is OFF. Memory snapshot will not work.
Warn  (criu/cr-check.c:1061): Do not have API to map vDSO - will use mremap() to restore vDSO
Warn  (criu/cr-check.c:1029): CRIU built without CONFIG_COMPAT - can't C/R ia32
Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.
