Hello

Manual says:
     SYNOPSIS
          import [ -abcC ] [ -f ] system file [ mountpoint ]
that is, `import' allows C option.

On the other hand, we will find in /sys/src/cmd/import.c:
void
main(int argc, char **argv)
{
	char *mntpt;
	int fd, mntflags;

	mntflags = MREPL;
	ARGBEGIN{
	case 'a':
		mntflags = MAFTER;
		break;
	case 'b':
		mntflags = MBEFORE;
		break;
	case 'c':
		mntflags |= MCREATE;
		break;
	case 'f':
		fflag = 1;
		break;
	default:
		usage();
	}ARGEND;

Is the absence of C option in the source is a simple bug?

By the way, it is required as much as 60 sec to connect to my host `ar'
from my home plan9 terminal via ISDN line.
It seems IL does not reach  `ar'. Therefore I am using TCP.
	term% import  tcp!ar /n/kfs /n/ar
The connection time is same when I put `f' option to `import'
On the other hand, cpu command
	term% cpu -h tcp!ar -a netkey
responds without any delay.
Are there any reasons `import' requires much connection time?
