FreeBSD tbone.egroups.net 3.3-STABLE FreeBSD 3.3-STABLE #3: Fri Oct 8 11:54:16 GMT 1999 root@tbone.egroups.net:/usr/src/sys/compile/TBONE i386
>Description:
In src/lib/libc/gen/getvfsent.c, the structure vfs_lkmdirs is:
static const char *vfs_lkmdirs[] = {
"/lkm",
"/usr/lkm",
0,
0
};
vfspath() uses this as the list of directories to search. If the
user is root, the value of the environment variable LKMDIRS is appended
to the list.
Obviously, /lkm is nonexistent on 3.X and later systems. As a result,
when mount_msdos() (or any mount_*) tries to dynamically load the
FS module, it runs into the error.
For some reason it works as root but gives a cryptic 'No such file or
directory' error when attempting to mount as a user, regardless of
vfs.usermount sysctl.
>How-To-Repeat:
Mount a filesystem with an unloaded KLD module but not compiled into
the kernel, such as msdos.
>Fix:
Change references to 'lkm' to 'modules'.
WORKAROUND: ln -s /modules /lkm
