Your proposed patch is certainly much cleaner than grepping linux-gate away. If I understand the linux-gate concept correctly, its an area of memory mapped into application process space not based on a segment in an object file, but based on a prototype the kernel provides. What mkinitrd should recognise is that there's no file listed that the shared library resolves to. A pattern such as / = \(0x/ should recognise these cases and still maintain current behaviour with regard to LD_LIBRARY_PATH. Incidentally, there may be another ldd related bug waiting to happen. Currently, mkinitrd accepts ldd 2.3.2 output that look like this: /lib/ld-linux.so.2 = /lib/ld-linux.so.2 (0xb7fea000) But in ldd 2.3.3, that output format will change to this (tested in Fedora FC3): /lib/ld-linux.so.2 (0x0056f000) Perhaps that pattern should also be matched.

Bug#295412: initrd-tools: Fails to ignore 32bit emulation layer on ldd calls
Package: initrd-tools
Version: 0.1.77
Severity: important
Tags: patch
Hi,
when running a 64bit kernel with 32bit userspace on i386 the ldd
output includes the 32bit emulation layer as linux-gate.so library
without any realy file and mapped to 0x. Since mkinitrd tries
to cpio all {$3} from the ldd output it fails with (0x) being
missing.

[EMAIL PROTECTED]:~% sudo chroot /var/chroot ldd /bin/sh
linux-gate.so.1 = (0x)
libncurses.so.5 = /lib/libncurses.so.5 (0x55572000)
libdl.so.2 = /lib/tls/libdl.so.2 (0x555b1000)

/lib/ld-linux.so.2 = /lib/ld-linux.so.2 (0x5000)

The attached patch filters out the extraneous entry from the ldd
output.

This seems to be a dup of #279382.
Assuming that valid shared library paths start with '/'
I would suggest to apply this patch to mkinitrd:
