Hi,
It seems to me that there exist some kind of "fake" or "magic" translators
which show up "automatically". Consider the following output where "t" is a
read-only filesystem:
ludo@hurd:~/trans/tarfs/t$ ll
total 3
-rw-r--r-T 1 root 300 1024 Jun 15 1994 !-type-old-file
-rw-r--r-T 1 root 300 1024 Jun 15 1994 0-type-file
-rw-r--r-T 1 root 300 1024 Jun 15 1994 1-type-hardlink
lrwxrwxrwx 1 root 300 4 Jun 15 14:13 2-type-symlink -> file
crw-r--r-- 1 root 300 0, 0 Jun 15 1994 3-type-cdev
brw-r--r-- 1 root 300 0, 0 Jun 15 1994 4-type-bdev
drwxr-sr-x 2 root 300 0 Jun 15 1994 5-type-dir/
prw-r--r-- 1 root 300 0 Jun 15 1994 6-type-fifo|
-rw-r--r-- 1 bin sys 10240 Jun 15 14:31 7-type-contfile
ludo@hurd:~/trans/tarfs/t$ showtrans *
!-type-old-file
0-type-file
1-type-hardlink
2-type-symlink: /hurd/symlink file
3-type-cdev: /hurd/chrdev 0 0
4-type-bdev: /hurd/blkdev 0 0
5-type-dir
6-type-fifo: /hurd/fifo
7-type-contfile
/hurd/???dev do not exist, and /hurd/symlink is not running (not that
the netfs_set_translator() callback of this filesystem *always* returns EROFS
without doing anything). So where do they come from?
However, it seems that a fifo translator was started (how?) wich causes the
following:
ludo@hurd:~/trans/tarfs$ settrans -g t
settrans: t: Device or resource busy
Could someone explain me what happens here?
Thanks,
Ludovic.
