Description Per Steinar Iversen 2000-06-21 04:15:14 EDT
mkinitrd does not detect linear raid in /etc/raidtab. 

It is also sensitive to TAB/SPACE in raidtab.

The following modification solves these problems, note that mkinitrd
contains a tab, so that the bugzilla web interface will
probably slightly destroy this diff.

                echo "raid level $number (in /etc/raidtab) not recognized"

This works well here, people using the linear raid facility have less
problems with updating kernels.

Comment 2 Erik Troan 2002-05-21 18:13:21 EDT
fixed (finally!) in mkinitrd 3.3.11

we don't have any linear raid machines around here though, so it hasn't been
thoroughly tested -- patch is nearly identical to yours though
