Hi,
Sorry, I haven't found dbootstrap in the BTS, and it's late.
I try to install debian 3.0 on a non standard mipsel target (IDT r4k based).
There's net and IDE support, no floppy. My custom kernel is already working
fine.
Actually, I've downloaded the bf-pre3.0.20cvs20020217 root.bin,
dd'ed to a temporary partition, and booted with "root=/dev/hdc2".
Well, the problem is with dbootstrap. It segs fault if there's no cdrom
drive attached to the IDE chain. Following is a strace of dbootstrap
illustrating the problem. The bug seems to lie with the content of
/proc/sys/dev/cdrom/info.
open("/proc/sys/kernel/osrelease", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x2aac4000
read(3, "2.4.17-mips\n", 1024) = 12
close(3) = 0
munmap(0x2aac4000, 4096) = 0
open("/proc/cpuinfo", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x2aac4000
read(3, "system type\t\t: IDT Homelink\nproc"..., 1024) = 249
close(3) = 0
munmap(0x2aac4000, 4096) = 0
open("/proc/sys/dev/cdrom/info", O_RDONLY) = 3

0x2aac4000

Now, if I plug an old crappy CDROM drive along to my hdc HD,
dbootstrap works fine. Here's the content of the troublesome proc file,
in the event it helps in fixing dbootstrap source code.
