Kutulutsidwa kwa zida za CRIU 3.16 (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:
- Onjezani lamulo la criu-ns kuti mubwezeretse chithunzithunzi chosungidwa ndi PID yatsopano komanso pamalo ena okwera. Kuyambira ndi PID yosiyana kungakhale kofunikira, mwachitsanzo, ngati PID yakale ikugwiritsidwa ntchito kale mu dongosolo.
- Kuthekera kosunga ndikubwezeretsanso zithunzithunzi zamawonekedwe a zida zankhondo zakhazikitsidwa.
- Kuletsa kutsekereza ndikutsegula kwazinthu zama netiweki kutengera nftables.
- Thandizo lowonjezera pakubwezeretsa zida zomwe zidapangidwa kale.
- Thandizo lowongolera pobwezeretsa zotengera ku mapoto omwe alipo.
- Kwamakasitomala a RPC, kuthekera kodziwa kugwiritsa ntchito PID kwawonjezeredwa, kukhazikitsidwa pogwiritsa ntchito makina a pidfd.
- Chilolezo cha mafayilo onse a proto pazithunzi/chikwatu chasinthidwa kukhala MIT.
