hello<br><br>I want to boot linux without ramdisk. <br><br>The purpose not using ramdisk is to speed up the boot time of my computer while <br>
Load the ramdisk used about 15s in my computer.<br><br>The system have start up successfully, but there are some problems:<br><br>I have boot my system by add <br>root=/dev/sda2<br>fastboot<br>read-write to /boot/silo.conf<br>
<br>root=/dev/sda2 is bad on multi-disk servers, so I want to know is there any way<br>possible to use uuid as the root device when ramdisk is no used?<br>
<br>use read-write is because the /sbin/init in userspace filesystem can't run successful <br>when the filesystem is mounted readonly. but in a system with ramdisk, the root <br>filesystem is mounted read only when init, why can't mine?<br>
as i know, the ramdisk is died after the switch_root program run.<br><br>use fastboot is to skip the fsck, because run fsck on a mounted filesystem is bad. but no fsck is not good, I really want to know how does the system check the filesystem exactly after the filesystem is mounted.<br>
<br>sometimes boot error:<br><span lang="en"><span>ata1.00: qc timeout (cmd 0xec)<br>ata1.00: failed to IDENTYFY (I/O error, err_mask=0x4)<br>ata1: SATAlink up 3.0 Gbps (SStatus 123 SControl 0)<br><br>any help?<br>thanks!<br>
