RE: Change the order of scsi Controller
as Etch uses udev for managing hardware, why not use symbolic names for your
partitions (based on the file system label)? This works even in initrd, if
you use initramfstools, it does not work with yaird!
On my Alphastation I have the following kernel bootlines in aboot.conf:
thetaphi@alpha:/boot$ cat etc/aboot.conf
# aboot default configurations
0:2/vmlinuz ro initrd=/initrd.img root=LABEL=root
1:2/vmlinuz.old ro initrd=/initrd.img.old root=LABEL=root
And the following fstab:
thetaphi@alpha:~$ cat /etc/fstab
# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
LABEL=root / ext3 defaults,errors=remount-ro 0 0
LABEL=boot /boot ext2 defaults,noatime,nodiratime 0 0
LABEL=var /var ext3 defaults 0 0
LABEL=home /home ext3 defaults 0 0
LABEL=swap none swap sw 0 0
The labels were assigned to all partitions e2label and for swap by mkswap.
That was it. Works stable and I can change my hardware configuration
whatever I like (because sometimes the order changes with every reboot when
parallel searching for new devices is enabled).
I use this style for all my machines (not only the alpha one).
