Kutulutsidwa kwa zida za CRIU 3.18 (Checkpoint and Restore In Userspace) zomwe zidapangidwa kuti zisunge ndikubwezeretsanso njira pamalo ogwiritsira ntchito, zasindikizidwa. Chida chothandizira chimakulolani kuti mupulumutse gawo limodzi kapena gulu lazinthu, ndikuyambiranso ntchito kuchokera pamalo osungidwa, kuphatikiza mutayambiranso dongosolo kapena pa seva ina popanda kuphwanya maukonde omwe adakhazikitsidwa kale. Khodi ya polojekitiyi imagawidwa pansi pa layisensi ya GPLv2.
Pakati pa madera ogwiritsira ntchito ukadaulo wa CRIU, zimadziwika kuti OS imayambiranso popanda kusokoneza kupitiliza kwa njira zomwe zatenga nthawi yayitali, Kusuntha kwamoyo kwa zida zakutali, kufulumizitsa kukhazikitsidwa kwa njira zocheperako (mutha kuyamba kugwira ntchito boma lopulumutsidwa pambuyo poyambitsa), kukonzanso kernel popanda kuyambiranso ntchito, kupulumutsa nthawi ndi nthawi kuti ntchito zamakompyuta ziyambenso kugwira ntchito pakagwa ngozi, kulinganiza katundu pamagulu m'magulu, kubwereza ndondomeko pamakina ena (foloko ku a remote system), kupanga zithunzithunzi zamapulogalamu ogwiritsa ntchito powasanthula padongosolo lina kapena ngati mungafunike kusiya zina mu pulogalamu. CRIU imagwiritsidwa ntchito pamakina owongolera ziwiya monga OpenVZ, LXC/LXD, ndi Docker. Zosintha zofunika kuti CRIU igwire ntchito zikuphatikizidwa m'gulu lalikulu la Linux kernel.
M'kutulutsa kwatsopano:
- Anapereka mwayi wogwiritsa ntchito CRIU popanda ufulu wa mizu.
- Thandizo lowonjezera la chizindikiro cha SIGTSTP (chizindikiro choyimitsa cholumikizira, chomwe, mosiyana ndi SIGSTOP, chimatha kugwiridwa ndikunyalanyazidwa).
- Onjezani gawo "--skip-file-rwx-check" kuti mudumphe kuwona zilolezo zamafayilo (r/w/x) pobwezeretsa.
- Thandizo lowonjezera pazosankha za IP_PKTINFO ndi IPV6_RECVPKTINFO.
- Thandizo la ma breakpoint a hardware lakhazikitsidwa pamapulatifomu a ARM.
- Kukhathamiritsa kosungirako kwamafayilo ochepa kwambiri (-ghost-fiemap).
