Hackers,
Simple question: should tar dump core if it tries to
access /proc where /proc is, of course, mounted as a
procfs?
I am going to start to sup the -current tree, so I
wanted to backup my entire system. I cd to / and
simply issued `tar cvf /dev/rst0 .i >& tar.log &'. The system
barfed on /proc. If /proc is unmounted the tar executes
as expected. The following error message is printed
to the console.
Jan 30 16:29:31 troutmask /kernel: pid 115: tar: uid 0: exited on signal 11
Will a similar type of error occur with unionfs and memfs?
On other note. I have built several programs from prep.ai.mit.edu
(octave-1.1.0, Gnu make-3.71.1), ftp.cs.umb.edu (Karl Berry's distribution
of TeX, dvipsk, and xdvik), and ftp.x.org (xfig-3.1.2, transfig-3.0)
with very few problems. I quite impressive and thankful for the
core team's sweat.
One minor problem: Some programs include the following lines:
#include <stdio.h>
int foo() {
extern char *sys_errlist[];
....
}
FreeBSD-2.[01].x declares
extern __const char *__const sys_errlist[];
in stdio.h. gcc complains about the redeclaration, then halts
compilation. I modified the sources to read
#include <stdio.h>
#include <sys/param.h>
int foo() {
#if BSD < 199303
extern char *sys_errlist[];
#endif
....
}
Is this the proper way to handle the problem?
Finally, I have unsubscribed to -hackers because of my $real$ work load.
Please, email any response to me. I will re-subscribe when life
calms down.
