Package: sysvinit
Version: 2.88dsf-5
After debootstraping testing/squeeze there's a problem when trying to
start it under OpenVZ. init starts but the rc scripts fail to properly
setup environment (run scripts from runlevel S and runlevel 2).
OpenVZ's vzctl enter VEID dies with the following error message:
# vzctl enter 1050
enter into VE 1050 failed
Unable to open pty: No such file or directory
(the above if caused by /dev/pts not being mounted)
I've narrowed the problem to startpar program which is used by init
scripts to run scripts for given runlevel in parallel. It seems that
startpar dies giving an error :
17 rt_sigaction(SIGWINCH, {0x401f40, [],
SA_RESTORER|SA_RESTART|SA_NODEFER, 0x7fcad974cf80}, NULL, 8) = 0

17 write(3, "tcgetattr: Inappropriate ioctl for device\n", 42) = 42

I'm attaching full strace output of startpar.
I've browsed Debian's sysvinit source and found out this call to
tcgetattr():
///
if (tcgetattr(0, &tio))
{
perror("tcgetattr");
exit(1);
}
///
tio variable is later used to disable basic terminal output translation:
///
tio.c_oflag &= ~OPOST;
if (tcsetattr(1, TCSANOW, &tio))
perror("tcsetattr");
///
When I comment this code and rebuild the package then the virtual
environment boots
successfully. I suppose that OpenVZ's "stdin"/"stdout" for init
program isn't a regular terminal
and that's the cause of tcgetattr() failing.
Should it be a fatal error if a call to tcgetattr() fails? Maybe we
could just detect the case when tcgetattr() returns 0 and if such
thing occurs - omit using tcsetattr()?
There's also one note that adding:
CONCURRENCY=none
to /etc/default/rcS
makes the system boot properly.
Host node runs Lenny and it works well. Below is the information about
