Dotaz: GNU/Linux a FreeBSD

[Lukas]

Snazil jsem se neco vygooglit, ale stale porad nechapu v cem je nejmarkantnejsi rozdil mezi Tuxem a BSDckem.. Podle screenshotu to pouziva stejne WM, mozna ze to ma i stejny Kernel.. Krome jineho loga me moc nenapada..

No prave ze kernel to ma uplne jinej

[jyrki]

prave rozdil je v tom kernel a take v userlandu. Linux pouziva userland GNU, BSD pouzivaji kupodivu userland BSD. Rozdil je napr jeste ve startovacich skriptech, Linux pouziva System V-like startovaci skripty. Jak Linux, tak BSD maji sve vlastni bootloadery.
Linuxove jadro bylo napsano "from scratch", Free/Net/OpenBSD jsou pohrobci BSD386 ktery vychazi z Net/2, tedy unixoveho OS prepsaneho tak, aby neobsahovalo zadny kod na ktery vlastnil licenci Novell (odkoupil od AT&T). Net/2 bylo Novellem uznano jako pravne "ciste".

mozna ze to ma i stejny Kernel..

Stejny?? To asi ne!! BSD (Open,Free,NetBSD) vychazi ze systemu BSD4.4 ktery byl vyvinut, pokud se nepletu na univerzite v Berkeley.

Linux vychazi z Minixu (uplne neco jinyho nez BSD4.4!!)

[jyrki]

Dovolim si poopravit, Linux byl napsan puvodne v Minixu, ale je psan from scratch, to ovsem nemeni nic na tom ze je to uplne neco jineho nez BSD. A pravdu mate naopak Vy ohledne Free/Net/OpenBSD, vychazi samozrejme z 4.4BSD Lite a neobsahuji zadny kod 4.3BSD (Net/2).

Takže v čem je ukryta výhoda proti GNU/Linuxu? Vím- Srovnávat se to nedá, všechno je o volbě, ale přece jenom něco to má třeba propracovanějši.. Co používá BSD za správce balíků (Jestli tedy něco takového má)..

[Vykook]

V nicem, teda ve vetsi rozsirenosti. Ja osobne preferuju FreeBSD. Ma system portu z ktereho vyslo Gentoo s portage. Obsahuje ted pres 16000 portu.

[martyr]

Zde bychom se pousteli do mensiho flamu, takze to zkusim rict takhle. Uzivatele FreeBSD rikaji ze je stabilnejsi, cisteji napsane, da se rici ze je lepe zdokumentovane (Handbook - predevsim ma jednu oficialni dokumentaci). Nekomu muze vyhovovat treba to ze je to jeden operacni system, neni zde problem s kompatibilitou jako mezi nekterymi distribucemi Linuxu. Predevsim je to ovsem o tom, ze tem co ho pouzivaji, vyhovuje vic, takze vyzkousej a uvidis sam.
Balickovaci system to ma vlastni, uz tu byly zmineny Ports, samozrejme jdou instalovat i binarni balicky, zavislosti si to pohlida.

[Martin Lebeda]

Ano, je to vevnitř jiné, navenek z 90% stejné. BSD Userland, jak někdo psal výše se týká hlavně základních utilit (ls, cp, mkdir, find ...), ale i ty GNU lze snadno doinstalovat z předpřipravených balíků/portů. Zbytek je stejný, takže samozřejmě že "wm" (např. fluxbox) je na většině unixů stejný sw (pořád to je fluxbox), pouze kompilovaný pro příslušný OS.

Já osobně tvrdím, že mezi FreeBSD a Linuxem je podobný rozdíl jako různými distrobucemi samotného Linuxu, pokud se bavíme o pohledu uživatele. FreeBSD mi přijde jako něco mezi Slackware, Gentoo a Debianem. Z pohledu uživatele mezi Linuxové distribuce spolehlivě zapadne. Mě osobně na FreeBSD vyhovuje (přešel jsem RH->Debian->Slackware->FreeBSD) handbook, jednoduchost (jako Slackware nebo archlinux), má mnoho (16328 portů - http://www.freebsd.cz/cs/ports/index.html) připraveného sw vč. propracovaných závislostí v portech (jako gentoo) i v předkompilovaných balících (14053 binárních balíků v amd64 verzi) (jako debian) takže nemusím kompilovat pokud nechci. A navíc mi komunita kolem něj přijde fajn a méně fanatická než někteří kolem linuxu. Navíc má dost spolehlivou implementaci API Linuxu, takže běžný sw, který je pouze pro linux a pouze binární také funguje (osobně využívám Operu a AdobeReader, údajně funguje i takový Oracle apod., nejdou věci kolem jádra, třeba vmware a pochopitelně ovladače)

Pokud jde o stabilitu, tak je stejná jako Linuxu - spíše pověst než realita, jako ostatně všude s vyjímkou windows (tam je pověst ještě horší než realita Minimálně svou instalaci FreeBSD jsem schopen vhodnou kombinací kroků spolehlivě zatuhnout, ale to linux také a mám podezření, že to souvisí s hw). Pokud svůj hw rozchodíte ve Slackware, pak jej na 99% budete schopen rozchodit i ve FreeBSD.

[Vykook]

No jeste bych doplnil ze pro serverove(nejen) vyuziti ma par super funkci ktery pro linux nejsou/nebo se musi opatchova jadro. jako bezpecnostni urovne behu, jail, vetsi vyber paketovych filtru(PF je vazne super. nevite nekdo o portu na linux?) a snapshoty FS(je mozny ze to nejakej linuxovej fs ma, ale ja o zadnym nevim)
