Hi, the best is to not use the (I call it "deprecated") old-style linux device names. Use /dev/disk/by-uuid/.... for the specification of the root filesystem (each filesystem has a unique ID assigned on creation). Alternatively assign a name to the file system using tune2fs/e2label and specify as /dev/disk/by-name/...., so it has a nice name. The management of the symbolic links in /dev is done by UDEV which is booted by the initrd.
Here is my aboot config of the kernel line on my AlphaStation (should be similar with MILO): 0:2/vmlinuz ro initrd=/initrd.img root=/dev/disk/by-label/root These directory listings are dynamically created by UDEV, so you should prefer these ones. Recent installations of Ubuntu (not sure if also Debian) automatically use them: theta...@alpha:~$ ls -l /dev/disk/by-label/ insgesamt 0 lrwxrwxrwx 1 root root 10 8. Jun 07:27 boot -> ../../sda2 lrwxrwxrwx 1 root root 10 8. Jun 07:27 root -> ../../sdb1 theta...@alpha:~$ ls -l /dev/disk/by-uuid/ insgesamt 0 lrwxrwxrwx 1 root root 10 8. Jun 07:27 09311049-3762-4d4d-877e-a4b02a4db4f1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 8. Jun 07:27 b8c0bb84-297a-44e5-b83e-d7aa1e352248 -> ../../sda2 If you have multiple network cards it's also a good idea to assign static names using UDEV configuration based on their MAC address, ethX is ugly :-) ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: [email protected]> -----Original Message----- > From: Piotrek Gliźniewicz [mailto:[email protected]] > Sent: Monday, June 21, 2010 10:04 PM > To: [email protected] > Subject: Re: Upgrading Sarge to Etch - failing to boot new kernel > > >>> Another option: Could you try "linux-image-2.6-alpha-legacy" instead > >>> of -generic?
