Kuye kwaziwa ukuba ubuthathaka bufunyenwe kumyalelo weSudo (umsebenzisi omkhulu) weLinux. Ukusetyenziswa kobu buthathaka kuvumela abasebenzisi abangenalungelo okanye iinkqubo ukuba baphumeze imiyalelo enamalungelo omsebenzisi ophezulu. Kuqatshelwe ukuba ubuthathaka buchaphazela iinkqubo ezinoseto olungekho mgangathweni kwaye abuchaphazeli uninzi lweeseva eziqhuba iLinux.
Ukuba sesichengeni kwenzeka xa useto loqwalaselo lweSudo lusetyenziswa ukuvumela imiyalelo ukuba yenziwe njengabanye abasebenzisi. Ukongeza, i-Sudo inokulungiswa ngendlela ekhethekileyo, ngenxa yokuba kunokwenzeka ukuqhuba imiyalelo egameni labanye abasebenzisi, ngaphandle kwe-superuser. Ukwenza oku, kufuneka wenze izilungiso ezifanelekileyo kwifayile yoqwalaselo.
I-crux yengxaki ilele kwindlela i-Sudo ephatha ngayo ii-ID zabasebenzisi. Ukuba ufaka i-ID yomsebenzisi -1 okanye elingana nayo 4294967295 kumgca womyalelo, umyalelo owuqhubayo unokuphunyezwa ngamalungelo omsebenzisi ophezulu. Ngenxa yokuba ii-ID zomsebenzisi ezikhankanyiweyo azikho kwidathabheyisi yegama eliyimfihlo, umyalelo awuzukufuna igama lokugqitha ukuze usebenze.
Ukunciphisa amathuba okuba nemiba enxulumene nobu sesichengeni, abasebenzisi bayacetyiswa ukuba bahlaziye i-Sudo kwinguqulo ye-1.8.28 okanye kamva ngokukhawuleza. Umyalezo uthi kwinguqulelo entsha ye-Sudo, i-parameter -1 ayisasetyenziswa njenge-ID yomsebenzisi. Oku kuthetha ukuba abahlaseli abayi kukwazi ukusebenzisa obu buthathaka.
