pendrive linux

A /var/log az kulonosen mokas mivel a programok egy resze nincs felkeszulve arra, hogy nincs meg a log konyvtaruk/filejuk. Szoval kell egy init script ami rendbeszedi a dolgokat bootolaskor. A debian-ban levo skeletont hasznaltam ami kicsit overkill szamomra szoval kicsit paraszthackesen osszaraktam valamit:

#! /bin/sh

Eddig rendben is volnank elnevezzuk log-init-nek a scriptet es berakjuk szepen a mountall.sh utan ez nalam a rcS.d/S38log-init. A befejezesnel opcianlisra hagytam a do_backup-ot hiszen az sok idot is igenybe vehet nem beszelve a gyakori rebootoknal mindig uj file krealodik felhasznalva ertekes write cycleoket. A logokat cronnal havonta egyszer backupolom a do_backup modszerrel.

A .bash_history es a .lesshst fileok helyett egy simlinket csinaltam /dev/null-ra. Hat itt allok jelenleg. Jelenleg meg csak nfs es samba kiszolgalo, de torrentfluxot, mpdt es icecastot akarok rarakni, hogy legyen minden egyhelyen. Ezek azert lesznek erdekesek, mert valamilyen sql kell hozza amihez szinten majd tmpfs-t kell hasznalni csak ott mar fontos, hogy valamilyen uton modon szinkronizaljuk a pendrivval, ha mas nem rebootkor. De errol majd akkor ha mar megoldottam a problemat.
