Hello list,
I am using uml in a setting where i am only interested in the output of
its console, and won't give it any console input.
I have encountered a phenomenon that if i pipe something to the uml
command the boot freezez at:
echo something | ./linux ......
.
.
.
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
*hang*
What would normally have appeard next is:
line_ioctl: tty0: ioctl KDSIGACCEPT called
INIT: version 2.84 booting
Activating swap.
Checking root file system...
fsck 1.27 (8-Mar-2002)
.
.
.
The same happens if i run the uml command from a perl-wrapper:
#!/usr/bin/perl
system("linux .....");
exit 0;
echo something | perl-wrapper.pl
... and it hangs at the same spot.
I understand that it is related to tty-allocation, but i could not find
any solution after trying with different con-settings. I seem to miss
something. So my question is, how do i get only the output and remove the
hang if the perl wrapper is piped to?
Thank you in advance.
Kyrre
