Re: AHCI driver progress report - hot-swap PM and parallel probe
I think we do need to be able to mount by serial number, or perhaps
have some sort of translation file in /etc so /etc/fstab can use short
names. The device iteration works fine for systems with one or two
disks, but after that it just gets too problematic as any drop-out
will renumber the da* devices.
I don't think we're gonna be able to get that in for 2.4, but the devfs
SOC project should make it possible for the kernel to create symlinks
within it for serial numbers during boot (before the filesystems go R+W),
and that plus a translation file in /etc would do the trick.
That reminds me, I have to add serial number probing support to
AHCI. It's a really easy step, I just have to fake the SCSI page
command that retrieves it and copy the information out of the ident
structure that it already collects (and prints to the console). The
peripheral driver could then issue the devfs link once devfs is
integrated.
