Sam Hartman, ved\u00faci projektu Debian, sa pok\u00fasil<\/a><\/noindex> pochopi\u0165 nezhody t\u00fdkaj\u00face sa dod\u00e1vky bal\u00edka elogind v r\u00e1mci distrib\u00facie. V j\u00fali t\u00edm zodpovedn\u00fd za pr\u00edpravu vydan\u00ed zablokoval<\/a><\/noindex> zaradenie elogind do vetvy testing, preto\u017ee tento bal\u00edk sp\u00f4sobuje konflikt s libsystemd. <\/p>\n

Pripom\u00edname, \u017ee elogind<\/a><\/noindex> poskytuje rozhrania potrebn\u00e9 na fungovanie GNOME bez in\u0161tal\u00e1cie systemd. Projekt bol zalo\u017een\u00fd ako odvetvenie od systemd-logind, presunut\u00e9 do samostatn\u00e9ho bal\u00edka a zbaven\u00e9 v\u00e4zby na komponenty systemd. Okrem toho elogind poskytuje svoju verziu kni\u017enice libelogind, ktor\u00e1 preber\u00e1 nieko\u013eko funkci\u00ed pon\u00fakan\u00fdch v libsystemd a pri in\u0161tal\u00e1cii nahr\u00e1dza t\u00fato kni\u017enicu. <\/p>\n

Za d\u00f4vody blokovania bol uveden\u00fd konflikt s bal\u00edkom systemd a nebezpe\u010denstvo nahradenia libsystemd alternat\u00edvnou verziou libelogind, ktor\u00e1 je \u00faplne nekompatibiln\u00e1 s p\u00f4vodnou kni\u017enicou na \u00farovni ABI.
\nV bal\u00edku elogind je ozna\u010den\u00fd ako konfliktuj\u00faci s kni\u017enicami systemd, ale je vo svojej podstate ur\u010den\u00fd na pr\u00e1cu iba bez systemd a konflikt so systemd dokonca prin\u00e1\u0161a v\u00fdhody, preto\u017ee neumo\u017e\u0148uje omylom nain\u0161talova\u0165 elogind. Na druhej strane v s\u00fa\u010dasnej podobe pokusy prostredn\u00edctvom APT aktualizova\u0165 konfigur\u00e1ciu zo systemd na variant so sysvinit a elogind ved\u00fa k z\u00edskaniu po\u0161kodenej s\u00fastavy<\/a><\/noindex> s nefunk\u010dn\u00fdm APT. Ale aj po odstr\u00e1nen\u00ed tejto nedokonalosti zost\u00e1va prechod od systemd k elogind nemo\u017en\u00fd bez odstr\u00e1nenia u\u017e nain\u0161talovan\u00fdch pou\u017e\u00edvate\u013esk\u00fdch prostred\u00ed.<\/p>\n

V\u00fdvoj\u00e1rom elogind bolo bola navrhnut\u00e1<\/a><\/noindex> prisp\u00f4sobenie elogind na pr\u00e1cu nad \u0161tandardn\u00fdm libpam-systemd, bez pou\u017eitia vlastnej vrstvy libpam-elogind. Prechodu elogind na libpam-systemd br\u00e1ni absencia podpory konceptu slice, ale v\u00fdvoj\u00e1ri elogind nechc\u00fa dosiahnu\u0165 \u00fapln\u00fa kompatibilitu s API a presne zopakova\u0165 v\u0161etky funkcie systemd, preto\u017ee elogind poskytuje iba minim\u00e1lnu funk\u010dnos\u0165 na organiz\u00e1ciu prihl\u00e1senia pou\u017e\u00edvate\u013eov a nepl\u00e1nuje zopakova\u0165 v\u0161etky subsyst\u00e9my systemd.<\/p>\n

Rie\u0161enie op\u00edsan\u00fdch technick\u00fdch probl\u00e9mov by malo by\u0165 rie\u0161en\u00e9 na \u00farovni interakcie t\u00edmu zodpovedn\u00e9ho za vydania a spr\u00e1vcov elogind a systemd, ale projektov\u00fd l\u00edder bol n\u00faten\u00fd zasiahnu\u0165, preto\u017ee sa t\u00edmy nedok\u00e1zali dohodn\u00fa\u0165, spolupr\u00e1ca sa zmenila na konfront\u00e1ciu a rie\u0161enie probl\u00e9mu sa dostalo do slepej uli\u010dky, kde m\u00e1 ka\u017ed\u00e1 strana svoj pravdu. Pod\u013ea n\u00e1zoru Sama Hartmana situ\u00e1cia pokro\u010dila do stavu, ktor\u00fd vy\u017eaduje v\u0161eobecn\u00e9 hlasovanie (GR, v\u0161eobecn\u00e9 uznesenie), v ktorom komunita rozhodne o alternat\u00edvnych syst\u00e9moch inicializ\u00e1cie a podpore sysvinit s elogind.<\/p>\n

Ak \u00fa\u010dastn\u00edci projektu zahlasuj\u00fa za diverzifik\u00e1ciu syst\u00e9mov inicializ\u00e1cie, v\u0161etci spr\u00e1vcovia bud\u00fa zapojen\u00ed do spolupr\u00e1ce pri rie\u0161en\u00ed tejto \u00falohy alebo bud\u00fa ur\u010den\u00ed \u0161peci\u00e1lni zodpovedn\u00ed v\u00fdvoj\u00e1ri na pr\u00e1cu na tejto problematike a spr\u00e1vcovia u\u017e nebud\u00fa m\u00f4c\u0165 ignorova\u0165 alternat\u00edvny syst\u00e9m inicializ\u00e1cie, ml\u010da\u0165 alebo vy\u0161etrova\u0165 proces. <\/p>\n

V s\u00fa\u010dasnosti u\u017e v repozit\u00e1ri sa nahromadilo<\/a><\/noindex> 1033 bal\u00edkov, poskytuj\u00facich servisn\u00e9 jednotky pre systemd, ale nezah\u0155\u0148aj\u00facich skripty init.d. Na vyrie\u0161enie tohto probl\u00e9mu pon\u00faka<\/a><\/noindex> by sa mali predvolene dod\u00e1va\u0165 service-s\u00fabory, ale pripravi\u0165 spracovate\u013e, ktor\u00fd by automaticky rozkladal pr\u00edkazy z t\u00fdchto s\u00faborov a generoval na ich z\u00e1klade skripty init.d.<\/p>\n

Ak sa komunita rozhodne, \u017ee v Debian dostato\u010dne podporuje jeden syst\u00e9m inicializ\u00e1cie, u\u017e sa netreba stara\u0165 o sysvinit a elogind, s\u00fastre\u010fuj\u00fac sa iba na jednotkov\u00e9 s\u00fabory a systemd. Tak\u00e9to rozhodnutie negat\u00edvne ovplyvn\u00ed porty, ktor\u00e9 nepou\u017e\u00edvaj\u00fa jadro Linux (Debian GNU\/Hurd<\/a><\/noindex>, Debian GNU\/NetBSD<\/a><\/noindex> a Debian GNU\/kFreeBSD<\/a><\/noindex>), ale v hlavnom arch\u00edve podobn\u00fdch portov zatia\u013e nie s\u00fa a nemaj\u00fa status ofici\u00e1lne podporovan\u00fdch<\/a><\/noindex>. <\/p>\n

Prepojenie na systemd tie\u017e zna\u010dne s\u0165a\u017euje zmenu smerovania v\u00fdvoja distrib\u00facie v bud\u00facnosti a obmedzuje vykon\u00e1vanie \u010fal\u0161\u00edch experimentov v oblasti inicializ\u00e1cie a spr\u00e1vy slu\u017eieb. Udr\u017eiava\u0165 elogind v prev\u00e1dzkovom stave je ove\u013ea jednoduch\u0161ie, ako ho odstr\u00e1ni\u0165 a potom sa pok\u00fa\u0161a\u0165 ho znovu prida\u0165. Ka\u017ed\u00e1 variantn\u00e1 mo\u017enos\u0165 m\u00e1 svoje v\u00fdhody a nev\u00fdhody, preto pred hlasovan\u00edm bude potrebn\u00e1 komplexn\u00e1 diskusia v\u0161etk\u00fdch argumentov za a proti.<\/p>\n
