that's really, really bizarre.  because you're the only person that seems to be
seeing this.

there's no mkdir -t anywhere in the spec file.
The only thing we have there is mkdir -p

in hex, p=0x70 and t=0x74   A single bit is different.  I'm wondering if perhaps
you have a memory error.  Is it repeatable?   Run memtest86 for a while ?

It is very repeatable.

I am running Fedora rawhide under KVM.

What happens if you run 'rpm -qa --triggers' and look for a 'mkdir -t'?

Also what is the output of the command 'which mkdir'?

Created attachment 313122 [details]
output of 'rpm -qa --triggers'

# which mkdir
/bin/mkdir

This is a "me too", though in my case, on real hardware with the PAE kernel.

Up until the xen changes yesterday, the installation used to complain about
ld-linux not being a symbolic link (though it was). That message no longer appears.

*** Bug 457500 has been marked as a duplicate of this bug. ***

What's the output of ls -R /etc/kernel?  And what dropped the files there (rpm
-qf /etc/kernel/*/* |sort -u)?

I cannot reproduce this bug with kernel-2.6.27-0.205.rc1.git2.fc10.x86_64 any
longer. Should I close this bug? Can darrel and jesse still reproduce this bug
with the latest rawhide kernel?

I am seing this with .205 and with .208 form koji:

It seems that something is removimg the symbolic link '/usr/lib/libply.so.1'
each time I try to install the kernel.  I put the link back, but it seems to get
removed somehow.

[root@localhost sbin]# ls -R /etc/kernel

BTW, the above was with kernel-2.6.27-0.208.rc1.git2.fc10.i686.rpm

I put a 'set -x' into /sbin/new-kernel-pkg and got the below trace.

Reverting mkinitrd, nash, etc. to *-6.0.55-2.fc10* and rerunning install:

[root@localhost Downloads]# 

I am seeing this too in my F10 LTSP client chroot.

bash-3.2# rpm -q kernel mkinitrd
kernel-2.6.27-0.205.rc1.git2.fc10.i586
mkinitrd-6.0.56-1.fc10.i386

With the exact same config file that I used with F9 mkinitrd.

bash-3.2# cat /etc/sysconfig/mkinitrd 
# Equivalent of the following:
#--with-avail==networking --net-dev=eth0 --rootfs nfs
--rootdev=192.168.0.254:/opt/ltsp/i386 --rootopts=noatime,dhcp
availmodules="=networking"
NET_LIST="eth0"
rootfs="nfs"
rootdev="192.168.0.254:/opt/ltsp/i386"
rootopts="noatime,dhcp"
BOOTPROTO="dhcp"

bash-3.2# mkinitrd -f /boot/initrd-2.6.27-0.205.rc1.git2.fc10.i586.img
2.6.27-0.205.rc1.git2.fc10.i586
mkdir: invalid option -- 't'
Try `mkdir --help' for more information.

Curiously when I run mkinitrd with the -v option I don't see the "mkdir: invalid
option" among the output.

Huh?

I can't reproduce this bug anymore with
mkinitrd-6.0.56-1.fc10.x86_64
kernel-2.6.27-0.226.rc1.git5.fc10.x86_64

Agreed, I can't reproduce anymore.
