Skriptik pre Porteus

30.6.2017 19:26 | Přečteno: 1111× | poslední úprava: 2.7.2017 07:06

Taky dlhsi skriptik pre Porteus, ktoreho cielom je kontrolovat priecinky s modulmy a ak dojde k zmene tak spusti halt systemu, taktiez funkcia repair ktora s pripojeneho USB kluca dokaze obnovit moduly ak je Porteus nainstalovany na pevnom disku.

[jose17]

a ja ze na taketo veci sluzi napr. github

[AsciiWolf]

Stále lepší, než například hloupé blogy o politice, které se tady vyskytují poměrně často.

[Petr Tomášek]

Skriptík asi bude fajn (a nemyslím si, že bys s tím musel hned na github a nesměl to publikovat tady, zas tak dlouhý to není), ale:

1) vůbec nevím co to Porteus je a předpokládám, že takových lidí bude víc, takže by možná neuškodilo to v 1-2 větách napsat a dát třeba odkaz. Taky vlastně vůbec nechápu, k čemu ten skriptík je - a třeba kdybych to pochopil, zjislit bych, že by mi to mohlo být užitečné. Takže mě osobně v tom zápisku tyhle "řeči okolo" chybí, abych vědět, jestli je to pro mně relevantní...

2) trošku mě zarazilo, že ve skriptu jsou natvrdo věci jako /dev/sda nebo /dev/sdb1 atd. To asi není moc přenosné/škálovatelné/obecné. Možná by stálo za to, když už to máš ve skriptu takhle natvrdo to nechat někde na začátku nakonfigurovat, aby když to někdo jiný bude chtít použít na jiné disky, aby mohl upravit jednoduše na jednom místě.

[lukve]

Porteus je distribucia podobna tej vasec z ciech s nazvom Slax, jedna sa o live zivu distribuciu ktora obsahuje moduly vytvorene pomocou squashfs tieto moduly obsahuju linuxovy system na rozdiel od napr ubuntu kde mas cd s ubuntu a jeden velky squashfs slax a Porteus riesia trochu inac init system tak ze pouizvaju AUFS a hldaju si ake nastanu zmeny a tie dokazu ulozit bud na particiu napr EXT4 ak z nej botuje alebo do dat suboru s takymto POSIX linuxovym filesystemom.

Mne sa tato myslienka velmi paci live distro a pouzivam to fulltime aj ako hlavny system na disku.

[lukve]

este dodam ze niektore vec iako firewall a podobne som "SKOPYROVAL" s LiveKit od Slaxu kedze IPTABLES velmi neovladam.

[Darth Phantom]

On Porteus ze Slaxu přímo vychází, první verze vyšly jako Slax Remix. Na rozdíl od Slaxu to ale není one man show a distro je stále vyvíjeno, na komunitní distribuci (která je celkem neznámá) mají celkem živé fórum. Páči sa mi naozaj ta modularita a cheatcodes. Možnost zavést komplet systém do RAM (to běží jako blesk). To je naozaj velmi pekné.

Největší kámen úrazu (alespoň pro mě) je softwarová základna. Ta se odvíjí od Slackware. Není jeden pořádný ucelený repozitář, leccos se musí pokoutně někde shánět. No a na to jsem zkrátka moc línej, shánět balíčky někde po všech čertech a nebo si je sám kompilovat :).

[skywaker]

Phantom ale vytvorit balicek je totalne jednoduche je to schquashfs ine su dependencies ale ak nevadi ze budes mat 100 modulova nie jeden velky tak je s tym menej roboty, vyhoda je skript txz2xzm a mergexzm super veci

[Petr Tomášek]

Zajímavé.

Jinak, možná by bylo bývalo stačilo, abys do první věty přidal před název "Porteus" slovo "distribuce" a pak by takoví hnidopiši jako já neměli důvod prudit .
