Re: lug-bg: Problem when replacing Init

[long@xxxxxx (Alexander Popov)]

Thanks na wsichi... no se oprawih... sorry i za zakysnenieto - skysah se da
rebootwam tezi dwa dena :))

Znachi w init/main.c replacenah /sbin/init s edin shell script kojto kato
#!/bin/sh polzwa ash - toj e naj malkoto koeto namerih

problema mi beshe w JDK - prosto ne mu stiga pamet...

 IBM J9, cvm, Jeode i nqkolko drugi VM si raboti kato pich - ideqta e towa
da se puska na industrialni kontroleri ili embedded platki s malko RAM.

Kogato smenih init sys moq script (server.sh) w obshti linii se nalozhi samo
da si inicializiram proc fs-to i eth0 - s taka napraweni neshta se spestqwat
blizo 2MB RAM!!! koeto za sistema s 8MB si e dosta...

Izbegnah slaganeto na ldconfig i ld.so.conf s LD_LIBRARY_PATH - okaza se che
towa si raboti perfektno...
Realno problemi s ENV nqmashe - prosto lipsata na /proc, /var i /tmp mi bqha
grizhata - ama ot kyde tolkowa akyl.... :))))
