Unfortunately it does not work. /dev/mapper/wwid entry is not created.
When I launch this manually from within initrd shell with -v2 I get:
: failed to get sysfs information
and this even does not work on the working system, I see the same
error. Quick strace shows:
stat("/sys/block/sda", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
lstat("/sys/block/^Z", 0x7fff65f44df0)   = -1 ENOENT (No such file or directory)
fstat(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 0), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x2af744b82000
write(1, "\32: failed to get sysfs informati"..., 35) = 35

It's a bit too late for me to dig into this today.
