Inkqubo engama-245 ifika noluhlu olukhulu lotshintsho kwaye ezi zezona zibalulekileyo

Abaphuhlisi abajongene nenkqubo ikhuphe ukukhutshwa kwenguqulelo entsha yenkqubo ye-245 eza noluhlu olukhulu lotshintsho olubandakanya iindaba ezinomdla kakhulu.

Kwinguqulelo entsha, Inkqubo entsha ye-homd kunye ne-systemd-distribu zongezwa, kubandakanya inkxaso yeeprofayile zomsebenzisi eziphathwayo kwifomathi yeJSON, ibonelela ngesakhono sokuchaza izithuba zamagama kwi-systemd-journald, yongeza inkxaso kwinkqubo ye "pidfd".

Yintoni entsha kwinkqubo ye-245?

Olunye lolona tshintsho lubalulekileyo kukongezwa kwenkonzo Inkqubo, yintoni pInikezela ngolawulo lwasekhaya oluphathekayo unikezwe ngohlobo lwefayile yomfanekiso onyusiweyo apho idatha ibhalwe khona.

Inkqubo e-homed ikuvumela ukuba wenze iimeko ezizimeleyo yedatha yomsebenzisi enokuhanjiswa phakathi kweenkqubo ezahlukeneyo ngaphandle kokukhathazeka malunga nexesha Izazisi kunye nemfihlo. Iziqinisekiso zomsebenzisi zibotshelelwe kulawulo lwasekhaya, hayi kuqwalaselo lwenkqubo.

Olunye utshintsho olubalulekileyo yile ukongeza icandelo lokongeza kwi-systemd-userdb, que Guqula ii-akhawunti ze-UNIX / glibc ze-NSS kwiirekhodi zeJSON kwaye ibonelela nge-Varlink API emanyanisiweyo yokubuza kunye neerekhodi zoluhlu.

Iprofayile yeJSON enxulumene nesikhombisi sasekhaya ciqulethe iiparameter eziyimfuneko ukuze umsebenzisi asebenze, kubandakanya ulwazi lwamagama, i-password hashes, izitshixo zokubethela, ii-quotas kunye nezixhobo ezibonelelweyo.

Kwelinye icala nako into entsha eluncedo "systemd-distribu" iyaqaqanjiswa, eyi diseña ukusasaza iitafile disk ukwahlula kwifomathi ye-GPT.

Ngale nto ulwahlulo lwesakhiwo luchazwa ngokungathandabuzekiyo ngeefayile ezichaza ukuba zeziphi izahlulo ekufuneka zibekhona okanye ezingafanele kubakho

Ukuziqhelanisa, inkqubo-distribu kunokuba luncedo kwimifanekiso yenkqubo yokusebenza eyaqala ingahanjiswa ngendlela encinci kwaye emva kokuqala kokuqala iyanda kubungakanani besixhobo esele sikhona okanye songezwa ngamaqhekeza ongezelelweyo.

Kwakhona kwi-systemd 245 ngoku kunokwenzeka ukuqhuba iimeko ezininzi zenkqubo-yejenali, nganye igcina iirekhodi kwindawo yayo yamagama. Ukongeza kwinkqubo ephambili ye-journald.service, isikhombisi senkonzo sinika itemplate yokwenza iimeko ezongezelelekileyo ezinxulunyaniswe kwizithuba zamagama abo kusetyenziswa umkhombandlela we "LogNamespace".

Inkqubo-udevd kunye namanye amacandelo ngenkqubo kongeze inkxaso ye indlela ye- nika amanye amagama kunxibelelwano lwenethiwekhi, ukuvumela amagama amaninzi ukuba asetyenziswe ngaxeshanye kunxibelelwano.

Igama linokufikelela kubalinganiswa abali-128 ubude (ngaphambili igama lomdibaniso womnatha lalilinganiselwe koonobumba abali-16). Ngokuzenzekelayo, i-systemd-udevd ngoku yabela kuthungelwano lwenethiwekhi nganye onke amagama ahlukileyo aveliswe zizikimu zokunika amagama ezixhasiweyo.

Oku kuziphatha kunokutshintshwa kwi-AlternativeName kunye ne-AlternativeNamesPolicy useto kwiifayile zelink Inkqubo-nspawn isebenzisa olunye igama lokuvelisa ngegama elipheleleyo lesikhongozeli sokubopha i-veth eyenziwe kwicala lomamkeli.

Eyokugqibela kodwa engancinananga, Ikwavelele Kwinkqubo yokubhengezwa engama-245 eyongeziweyo Inkxaso yesixokelelwano se Linux kernel "pidfd" Kwi-API sd-umcimbi.h ukusingatha imeko yokusetyenziswa kwakhona kwe-PID (i-pidfd ijoyina inkqubo ethile kwaye ayitshintshi, ngelixa i-PID inokubopha kwenye inkqubo emva kokugqiba inkqubo yangoku enxulumene nale PID).

Onke amacandelo enkqubo, ngaphandle kwe-PID 1, atshintshiwe asebenzisa ii-pidfds ukuba inkqubo esezantsi ngoku iyayixhasa le nkqubo.

Inkqubo-yokungena ngePolisiKit ibonelela ngolawulo lokufikelela ekusebenzeni kokutshintsha kwesiphelo. Ngokuzenzekelayo, iimvume zokutshintsha i-terminal esebenzayo zinikwa kuphela abasebenzisi abangene kwisiphelo sendlela ubuncinci kube kanye.

Ukwenza lula ukwenziwa kwemifanekiso ye-initrd ngenkqubo, umlawuli we-PID 1 ngoku umisela ukuba uyasetyenziswa kwi-initrd, kwimeko apho ilayisha ngokuzenzekelayo i-initrd.target endaweni yokungagqibeki.

Ukuba ufuna ukwazi uluhlu olupheleleyo yotshintsho kunye neendaba ezihanjisiweyo kolu khuphelo lutsha lwe-systemd 245, unokuqhagamshelana nabo Kule khonkco ilandelayo.
