Description Roland Nagtegaal 2005-05-19 08:14:47 UTC
/etc/conf.d/rc -> RC_DEVICE_TARBALL="no"
In a network with 60 gentoo machines, and all the same partitioning, some are
SATA and most are IDE. So I want all the same lines in /etc/fstab like this:
/dev/discs/disc0/part8   /usr reiserfs  defaults        0 0

Only: this works on IDE systems, because the symlink /dev/discs/disc0/part8 ->
../../hda8 will be created, but on SATA systems it will not. 

For IDE the (correct) behaviour can be traced to the script
/etc/udev/scripts/ but in /etc/udev/scripts/ their
seems to be no similar solution, or it may be broken. I don't really understand
those scripts yet.

Reproducible: Always
Steps to Reproduce:
1.On an SATA system, remove contents of /dev/, and reboot ls -al /dev/discs; it will not exist. ls -al /dev/sda*; those will exist

Actual Results:  
/dev/discs did not appear on SATA systems, but did on IDE systems

Expected Results:  
/dev/discs/disc0/ should have been populated with symlinks pointing to the right
device files (../../sdaX in SATA case, similar to ../../hdaX with IDE)
This means that one of the intended uses of udev does not work. In network
install, I loose a lot of generality that way, forcing me to keep all /etc/fstab
apart for all machines, while they could have been the same. Probably trivial fix.

I already notices this in Bug 92029, Comment #2

Ok, if you can come up with a fix, please let me know.

Otherwise, I'm going to mark this as CANTFIX, as I don't know how to do it.
