devfs vs pts
Не совсем в тему, но все же. Играюсь сейчас с linux devfs и появилась
трабла - не работают псевдоконсоли, может быть кто-нибудь сталкивался?
Вот кусок strace попытки запуска того же rxvt (из-под рута даже):
open("/dev/ptmx", O_RDWR) = 7
statfs("/dev/pts", {f_type="DEVFS_SUPER_MAGIC", f_bsize=4096,
f_blocks=0, f_bfree=0, f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0},
f_namelen=255}) = 0
statfs("/dev/", {f_type="DEVFS_SUPER_MAGIC", f_bsize=4096, f_blocks=0,
f_bfree=0, f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0},
f_namelen=255}) = 0
ioctl(7, SNDCTL_TMR_TIMEBASE, {B38400 opost isig icanon echo ...}) = 0
ioctl(7, TIOCGPTN, [0]) = 0
stat64("/dev/pts/0", 0xbfffe8d0) = -1 ENOENT (No such file or
directory)
fcntl64(7, F_GETFD) = 0
close(7) = 0
open("/dev/ptyp0", O_RDWR|O_NOCTTY) = -1 ENOENT (No such file or
directory)
...
open("/dev/ptyzf", O_RDWR|O_NOCTTY) = -1 ENOENT (No such file or
directory)
write(2, "rxvt: ", 6rxvt: ) = 6
write(2, "can\'t open pseudo-tty", 21can't open pseudo-tty) = 21
write(2, "\n", 1
) = 1
write(2, "rxvt: ", 6rxvt: ) = 6
write(2, "aborting", 8aborting) = 8
write(2, "\n", 1
) = 1
exit_group(1) = ?
