LiveCD aretise probleem - (lahendatud)

[karlsson]

Koostasin Debiani LiveCD baasil custom LiveCD iso tõmmise. Selle lasin dd abiga kõvakettale. Süsteem loetakse sealt ro reziimis. Aga mingi osa sellest opsüsteemist kirjutab oma andmeid kuskile. Näiteks, Debiani baasil Raspbian-i süsteemi osa sai läbi USB-i ühendatud selle arvutiga ja buutimisel loeti Raspbiani kujundus sellele custom Debianile. Ja see kujundus salvestati kuskile. Ja see olekski küsimus, kuhu? Kokku kettaid 4 (sda-sdc) ja partitsioone igal kettal umbes 2. Partitsioonid läbi uuritud ja juurkataloogides ei tuvastanud ka võõraid faile.
/dev/sdc1 sai dd abiga kopeeritud ja md5 kattus sellega mille samale partitsioonile lasin.
Seega kuhu on sellel LiveCd baasil aretisel võimalik veel andmeid salvestada?

kernel peab kuhugi süsteemilogisi ajutiselt laadima ja /tmp-i kasutavad rakendused.

[obundra]

Proovi veel seda Raspbiani kujundust muuta ja siis find käsuga leida näiteks viimase viie minuti jooksul muudetud faile:

Kood: Vali kõik

find / -cmin -5 -ls

Ilmselt ta kusagil tempis võib asuda, kui tmpfs on kettale mounditud, mitte otse mälusse.

Tänan. Niisiis, koomiline lugu. Tegelikult sai ka umbes samal ajal monitori DVI kaabel vahetatud VGA kaabli vastu. Kuna ekraani seadeid mingil põhjusel ei tuvastatud ja süsteem võttis madalama reso kasutusse, siis arvasin, et see on Raspbiani kujundus.
